How do I alter the galaxy wide population cap, where would it be located in the .XML files, and what would it be called inside the files? I feel like this is the only way to get what I want until some of the submods are updated

I know it adds a challenge, and some may scoff at cheating, but it's the way I like to play (plus a galaxy spanning factions only having so much space for units seems a little silly to me, but I guess you can hand wave that away with logistics and resources and such)

Trainers like WeMod only work with resources anymore, and Cheat Engine's tables won't activate for me. The only other thing I can seem to find online is is unit cap alterations in battle but that's not what I'm looking for.

Can anyone help? Thanks.
