Regex/Custom Affinity Premium Stash tabs

Hey.
When doing map rolling and/or sorting items I would love it if I could make a custom affinity by pasting in a regex string.

For example, I would 100% buy another map stash tab if I could sort between my rolled maps and unrolled ones easily.

I agree. They could use a overall update to stash tabs imo. There are many well thought out layouts ive seen online. Also we could use some affinity tabs like incubators since its been in the game for so long now.

This is a very good idea and it would open up a lot of item-sorting possibilities, potentially saving a lot of player time and effort in the long run.
