Introjucer can't do fat binary (32+64bit) plugin (VST/AU)?

How do i setup introjucer to build my AU and VST plugins as fat binaries for intel processors?
The “OSX Architecture” options has no intel 32/64 combo…

Choose “Universal binary 64 bit”

Ok, that was quite confusing. In XCode its called "Standard (32/64 bit-intel) - maybe you should call what it is?

Yes, sorry - I’ll change the wording for that!
