Would be really cool if you could box select filters in the inventory, that way you don't have to select every single item.

Copying it with ctrl+RMB and pasting with ctrl+LMB makes it a much easier task. Also, you can copy/paste whole boxes or wagon filters just like any other assembly recipe.

Or fill up the inventory with the items you want and center-click on each square to save that item as the filter.

You can do the same thing by holding the item and then middle clicking on slots you want filtered to that item.
