[Stash] Multiple Tabs with the Same Affinity

There should be an option to set multiple tabs with the same kind of affinity.

For example, I have 2 Unique items tabs, but I can only set the affinity to one of them.

My goal would be to have a main Uniques tab and a secondary Uniques tab and when moving an item from my inventory to the stash, if that Unique already exists in the first Uniques tab, it would get deposited on the 2nd tab instead of giving me an error and forcing me to add it manually.

Thank you!
