Range Check for spell that technically has no range?

[wintry jungle]

So I was going to add a range check to Channel Demonfire, only to find out it has no range applied to it on its tooltip. When I go outside of 40 yards though, I can still channel it...it just does no damage at all. Is there a way to add a range check from the target is indepedent of the spell's range itself? In other words, I can't use spell cooldown --> Spell in range --> false here

There's a default range check trigger, and a range check condition

40 yards should be available for all casters except evoker I guess
