I'n new to Diablo IV, I'm a Necro and I need help

In Diablo III I’m a Necromancer and I love the Skill “Devour / Devouring Aura” because it work on its own without pressing buttons… Is there the same thing in Diablo IV? I’m disabled with the use of one finger so the less buttons the better I play.

Basically I want to use Skeleton Mages with a skill to automatically sucks up Essence and Corpses is there anything like that in Diablo IV?
