Is your feature request related to a problem? Please describe.
When i'm using Applied Energistics 2 to automatize producing, I found that machines like extruder need an extruder shape to change output, but AE2 can't change it by itself, that means it need multipie machines to put material into different shapes.

Describe the solution you'd like
Add a button in GUI to switch whether to output non-consumed item into a new exportable slot.

Additional context

Just like this

make more machines

Weird af. Making more machines isn't a big deal at all if you play it right, let alone that's exactly why processing arrays and multiblock versions of each machines from GcyM are better than singleblock ones for it being able to have multiple buses in it, in order to handle the recipes with different NC items with Dintinct Buses mode enabled.

Building a Processing Array is better than making more machines
It can have many separated input buses so you can automate many recipes with different shapes with single extruder
