Is it possible to override the AppGen PRoJect system?

So I’ve written a template family which uses the appgen, but I noticed that the module(s) in an app file with 1 or more procedure is linked in automatically to the AppGen project settings.

Is there any way of stopping modules from being automatically added to the AppGen project?

I generate my own PRJ file and whilst I could include it into the AppGen project so it gets compiled first before the AppGen PRJ file, once the project system is running I’m not aware (so far) of anyway to stop it which means the user (programmer) gets an error and thus bad experience.

Besides if I could control the modules which were automatically linked into the appgen project file, I wouldnt need to write my own PRJ file, hence the question about controlling what modules get linked into the AppGen Project file.

TIA
