How would I go about changing unit upgrades on general? Specifically, I would like to be able to customize the amount of upgrades a unit can select, in amount of upgrades available per affinity tier or hybrid affinity, the specific stats for such upgrades, and to make it possible for an unit to go through all the affinity upgrades (being able to choose both upgrade choices as well as being able to go through all the affinities essentially eventually becoming a super unit with the cosmetics being the very last upgrade. Thanks in advance, and apologies if I missed a crucial tutorial I should have read. There seems to be no relevant mods to what I want to do.
