Stash Tab - "Reserve For..."

Since it is very very painful to sort everything in your stash tabs it would be really good if could reserve single spaces in your stash tabs for anything you want.

Currency for example:

You could easily reserve any field in a stashtab of your choice for any currency. That way it would be properly sorted right away.

Same goes for Essences and Maps.

It would still be worse than a currency stash tab since you couldn't store the same amount in normal stash tab. Therefor people would still buy those. But any f2p-player would a have a much better time browsing his inventory.
