it there a way to make units use upgrades mid game?

[helpmeplease]

im trying to make an rpg where creeps level up as you do. but i don't want to have to set upgrades used for EVERY single unit i use as a creep. is there a trigger that does this?


my trigger is

• event -a unit gains a level
  • condition - owner of leveling unit equal to player 1
  • set research level of creepupgrade to ((current research level of creepupgrade for neutral hostile)) +1) for neutral hostile)

but it isn't working. so im thinking it's because i need to set upgrades used on every unit i use..

Your creep units need to have the creepupgrade in order for it to work.
