An Item routing filter that would only check for the name of the item, nothing more.

This would allow you to name items (probably with an anvil) and send them to containers, regardless of what the item actually was, based on the name attached to it.

Example
Fred, Jeff and Sam want to set up item transfers between their respective locations.
Each sets up an input and an output chest, all chests are connected through a single master routing node.
Fred puts a Name Filter, that his output chest should only accept items named "Fred"
Jeff and Sam add those same name filters, with their own names respectively.
Fred wants to send a crate full of cobblestone to Sam, he puts the crate on an anvil and names it "Sam", then places it in his input chest.
Fred's output chest cannot accept it due to filter, Jeff's output chest cannot accept it due to filter, it goes to Sam's output chest.

Thank you for your time, consideration, and your mod.
