Compiler configurations in Projucer

Hi guys,

I would like to compile my plugin as VST3 for 32 and 64 bit, as AU for 32 and 64 bit, and as AAX for 64 bit only.

I can easily set up my VS / Xcode solutions to do this. However, this is something that should belong in my jucer project.

Is there a way to configure this from the Projucer which I am missing?
