Follower ignore mob rarity

In combat settings we can choose a global distance for our bots to approach mobs. I’d like there to be a global option for approaching mobs of different rarities, so we can ignore certain mobs and prioritise rare ones. For example:

White: 0
Magic: 0
Rare: 100
Unique: 100

This way, our follower aurabots can essentially act like combat is disabled until a rare mob appears. A sort of hybrid disable combat option.

My aurabot does 0 DPS but I want him to cast frost bomb and flame wall on rare+ mobs, but act like combat is disabled against anything lower rarity.
