New Red Stone Item

I feel it would be awsome if we had a new red stone item that you can craft and place on hoppers the objective of the item would be to sacrifice 5 items that don't get used but you can choose which 5 items can be excepted by the hopper for storage purposes basically making a useful item sorter say you have a mob grinder and you only want bones string arrows gunpowder and iron to be accepted into that hopper it'll only pickup those items off the ground and but them in the chest below so all those pointless items like armour that mobs drop don't Blick your hoppers and get in the way of all your sorting and collection needs. Of course as it woupd be connected to a hopper you won't be able to place any other Block to the side that the sorter is located on. I feel everyone else just like myself doesn't know why sorting with hoppers can't be made easier there are methods that take alot of Redstone but you'll only be able to select 1 item for that hopper and it's just a waste of the other 4 slots. Now if you only want 3 items to be excepted just use for say 1 bone 1 gun powder and 3 arrows now it'll only except those 3 items arrows filling up 3 of the 5 slots.
