Negative Healing on a Character

[shinjox]

Is there a way to give a character negative healing so that the effect is automated, as it does with npcs/creatures?

For example Undeath's Blessing.

Or, someone turned into a unique undead?

I'm not entirely sure what there is to automate - unlike in 1st edition, negative damage and positive damage never convert to healing directly, regardless of whether you have negative healing or not. So characters with negative healing are handled at the targeting level, by choosing to/not to target them with the healing effect.
