seperating lifedrain/siphon mana from the same cooldown

[jooster]

As the title says. I have been looking over these forums for about a hour and I don't know if my wording is wrong in the search. but i have been unable to find a solution. any help would be appreciated.

you could make it so when they use a ability on a target it makes a dummy caster and the dummy caster casts siphon mana or siphon life (only would need to do it for 1) and if its a item in the object editor there should be a thing called cooldown group and you could change the group its in.
