The "Character tab" an equipable stash tab

So I've recently started playing more so in a group, where some of the items we obtain are shared to maximize their usage. One of the things I find myself doing is trying to organize a tab so the gear looks proper and in the right spot, so its visible / easily accessible for the next person.

I think a cool idea for a stash tab, would be maybe 6-9 "mini-characters" where you can equip items into the proper items slots, within the stash itself, so you would have an inventory looking page inside of your stash to equip gear and keep it organized for different builds, sharing with your guild, or whatever else you may need.

I also was using the idol system this phrecia league, and we are sharing idols as well, we used white gems to mark out the idol slots that are blocked, just so it looked proper, perhaps an item that has no value or anything, that is just a part of the stash, but that you can place in a stash tab, infinitely usable to take up or lock a space, or perhaps lock / unlock a square in a tab to make it unusable, and customizable, so you can take a normal tab and turn it into a character tab with only the slots for the items, or similarly the idols.
