it would be nice to be able to add buff time. as example place 20 fish plate buffs on the same building just to be able to clear up star menu, this would give you 2x buff for 30 mins time 20 so 10 hrs. Also handy to say place 10 Snow buffs on a Granite pit. I would love to clear up my star menu of all these trash buffs ( fish plate, solid sandwich) that i have 100s of.
