How about an allocation filter?

After playing a while with groups I've realized that in many cases the loot allocation becomes a bit impractical, especially in maps.
Permanent allocation for uniques and most rares is completely fine.
But 4-link white stuff that maybe one person in the group needs? Or Scrolls of Wisdom and Portal Scrolls (there are plenty of people who don't even have them show in their item filter)?

So I'd very much like an allocation filter. That way the people who need scrolls can set them in the "allocate" mode and everyone else who only sometimes needs a scroll or two can set them to "make free for all". Or the standard low-tier rare stuff. Unless one is farming for chaos orbs it's not really relevant who exactly gets which half of the thirty yellow items.

It would add a bit more ease into farming/playing with friends. At least it would for me.
Am I alone in that?
