I have a sub process in my model and there is a drop-off block inside that (image). I want the drop-off element type could be set in model. I mean that I want to use this sub process in every part of model with different element types. so I used a parameter and set its type as an Agent and its control type is Agent Creator (image). but the problem is that in the drop-off element type field I cant use that because that parameter is unknown in that field.
