Ability to set permissions on multiple inventory items at once

I would really appreciate the ability to set permissions on multiple inventory items at once. Do this, and every content creator will bless you!

For example, I upload 40 new textures. They will all need to be set to +Copy, +Mod, +Resell, and "For Sale at L$30". Right now, I have to open the permissions on each one individually, and repeat the same series of clicks for every one of them!

This should work in a manner that when you multi-select items, any field where the information is initially different across them, like the description, should be grey, but editable. If you edit it, that field changes on all of them. The name field should not be editable in this manner, only the description and the various buttons for perms and the field for the selling price.
