Combuctor Custom Sets

[TrotskyIcepick]

Just switched from Bagnon to Combuctor + Combuctor_CustomSets and would like to know how to add items to the custom set if they don't already exist in my inventory, for example I would like a set containing all the ores I mine.

I'm guessing it has something to do with LIBITEMSEARCH rules, but honestly beyond that have no idea.

Thanks.
