Multiple Inno Setup Types that have optional Components

Question

I am trying to create a Inno Setup installer (with Inno Setup 6.2.0) that has multiple setup Types where more than one can have optional Components (as well as fixed components). For example, suppose I want to have the following setup types:

Instructor
Student

If the "Instructor" setup type is selected, I would like to have an "Instructor - Fixed" component (which must be installed), plus two optional components "Instructor- Optional 1" and "Instructor - Optional 2".

Similarly for the "Student" setup type, I would like a fixed component plus a couple of optional components.

Below is the starting point for my experiments:

[Types]
Name: TYPE_INSTRUCTOR ; Description: "Instructor" ;
Name: TYPE_STUDENT    ; Description: "Student" ;

[Components]
Name: COMP_INSTRUCTOR            ; Description: "Instructor"              ; Types: TYPE_INSTRUCTOR
Name: COMP_INSTRUCTOR\FIXED      ; Description: "Instructor - Fixed"      ; Types: TYPE_INSTRUCTOR ; Flags: fixed
Name: COMP_INSTRUCTOR\OPTIONAL_1 ; Description: "Instructor - Optional 1" ; Types: TYPE_INSTRUCTOR
Name: COMP_INSTRUCTOR\OPTIONAL_2 ; Description: "Instructor - Optional 2" ; Types: TYPE_INSTRUCTOR

Name: COMP_STUDENT            ; Description: "Student"                    ; Types: TYPE_STUDENT
Name: COMP_STUDENT\FIXED      ; Description: "Student - Fixed"            ; Types: TYPE_STUDENT ; Flags: fixed
Name: COMP_STUDENT\OPTIONAL_1 ; Description: "Student - Optional 1"       ; Types: TYPE_STUDENT
Name: COMP_STUDENT\OPTIONAL_2 ; Description: "Student - Optional 2"       ; Types: TYPE_STUDENT


[Files]
Source: "InstFixed.txt" ; DestDir: {app} ; Components: COMP_INSTRUCTOR\FIXED
Source: "InstOpt1.txt"  ; DestDir: {app} ; Components: COMP_INSTRUCTOR\OPTIONAL_1
Source: "InstOpt2.txt"  ; DestDir: {app} ; Components: COMP_INSTRUCTOR\OPTIONAL_2

Source: "StuFixed.txt" ; DestDir: {app} ; Components: COMP_STUDENT\FIXED
Source: "StuOpt1.txt"  ; DestDir: {app} ; Components: COMP_STUDENT\OPTIONAL_1
Source: "StuOpt2.txt"  ; DestDir: {app} ; Components: COMP_STUDENT\OPTIONAL_2

I have tried a few different things, but nothing has succeeded in achieving what I need. I have tried:

Adding Flags: iscustom to both setup types (my thinking was to indicate that both are customisable). However, Inno Setup only seems to allow for one customisable type.
Making just one of the setup type to have Flags: iscustom (e.g. adding it to TYPE_INSTRUCTOR). However, that does not work as I would like, because I can then end up with invalid combinations, e.g. I can select a mixture of Instructor and Student components.

The only way I can think to get around this is to have setup types for every possible combination. That would not be practical (this example is not my real problem, just a simple case to illustrate it, I would end up with a very large list of setup types).

Thank you in advance for any workable solutions.

That's not possible. At least not without some heavy customization with Pascal Scripting.

Way easier is to drop the Types altogether and use two top-level mutually-exclusive components and couple of optional subcomponents:

[Types]
Name: "custom"; Description: "Custom installation"; Flags: iscustom

[Components]
Name: "intructor"; Description: "Instructor"; Flags: exclusive
Name: "intructor\opt1"; Description: "Optional 1"
Name: "intructor\opt2"; Description: "Optional 2"
Name: "student"; Description: "Student"; Flags: exclusive
Name: "student\opt1"; Description: "Optional 1"
Name: "student\opt2"; Description: "Optional 2"
