[Suggestion] Preferred Buffs

I would like a method to be able to choose preferred buffs.

Middle ground between blocked buffs and no blocked buffs.

For instance, Spirit of Tala'Tak is overwritten by Flight of Eagles. I want Tala'Tak if available, but don't want to block Flight of Eagles. But if I have Tala'Tak already, don't overwrite with Flight of Eagles.
