Each time when I want to do multifit, then I have to do “buy all” first. But the problem is each time I have to manually check what I already have in station to deduct from “buy all”. This is frustrating, not necessary manual work. There should be an option to just not buy items which I already have when do “buy all” for fits.
Hmm, the multifit window does exactly this, buy all missing. I use this all the time, also to create a market bar folder, so I can shop the basket elsewhere.
