Trigger cooldown without the ability itself taking effect?

im using an ability which lets you swap between two units back and forth (they get replaced by trigger).
for a special reason i cant use the morph spell, so my problem are ability cooldowns which dont apply, as the unit is replaced.

is there a way to trigger this manually? i couldnt come up with anything yet.

maybe i could use a hidden spellbook with dummy spells having the same order string and order the unit to use them, but i dont think it will work well (if at all).

some help please

Don't replace the ability that morphs. That's it. You can't make a spell cooldown through triggers.

Engineering Upgrade with lots of different abilities makes it possible.
It's still pretty ugly to work with though.

I would highly recommend against trying to do it, unless it's for a single spell or something.
Then it might not be so bad.

There is 1 simple way to trigger a cooldown manually
Use the remove ability and add ability trigger.
Unit cast spell= remove ability or use disable ability trigger

There is a player -enable/disable ability
or unit - add ability trigger

basically remove/disable the ability, wait x seconds , then add/enable the ability again.
