If I open up the Properties of any arbitrary project, I'm able to change the Working Directory of any target project:
However, if I try to open up an individual Property Sheet for a project, the "Debugging" Category is missing, and I cannot find any field I can alter which would allow me to set the Working Directory for that Property Sheet (which would therefore allow me to change the Working Directory for multiple projects simultaneously):
What can I do to change this property at a Property Sheet level?
