How to enable a Research/Upgrade option per unit? I want to have a custom Research Y option for every instance of unit X. But, after fully "upgrading" a unit (the unit X itself has the custom Research Y available), the same Research Y is gone from any future instances of unit X?
I want to make every copy of a tower to be able to upgrade itself using the custom Research, but once any copy of that unit researches that upgrade, only the next level is available for any unit, instead of individually tracked research progress for each one.
