Is there either 1. A way to actively choose which among your GPs are consumed in a GA, or 2. A mechanic that would let you control that indirectly? For example, say I have two (2) Prophets, one (1) Merchant, one (1) Scientist, and one (1) Engineer. I want a GA immediately, which will cost two (2) GPs, but I know I'll need the Engineer and the Scientist soon. Is there a way (or a trick) to make SURE the Merchant and a Prophet get used?
