[Necromancer] Is it possible to change how targeting works for Siphon and Tether?

Wanted to use either of those abilities but since i have to directly look at a corpse to use them it just results in me flailing the camera around looking for a corpse in desperation.

Something that doesn't exactly feel fun in the heat of battle.

So is there any way to make their targeting like Bitter Harvest which just picks any available corpse in your vicinity?
