Select Mutiple Items in Inventory

This is basically just like it sounds, I would like to select multiple items quickly in my inventory so I can trash them. For example, while I grind I get a bunch of Fortuna gear that will never sell and is completely useless. As of right now, the most efficient way to discard these items is going to the nearest NPC with a shop feature and clicking them all quickly (still one by one). After grinding for hours on end you know that is the most tiresome thing in the world, and sometimes wish that mobs didnt even drop armor but then that would mess up the economy so I would like to say that adding a button that lets us select multiple items would make things much easier.
Thank you!!

 

A checkbox asking you if you want to do the same to the rest of the same items just like when you're processing.
