Cannot seem to adjust item stack size for filtering input/output on funnels. (Have not tested on Tunnels yet.)

-Add stack size functionality to filters to allow multiple outputs of same stack size?
(Ex. Filter that allows output of a stack of 9 crushed only outputting one type at at time.)

UPDATE: Can confirm same issue with Brass Tunnels.

My bad, issue was user error. Did not realize this was only possible when funnels were connected to belts.
