Explain your idea

I am sorry if it is implemented already in one way or another, but it would be great to have a way to empty item batcher by changing output mode

I do not understand this request, can you try to explain it in a little more detail please?

It seems I somehow skipped whole point of suggestion. My suggestion is to have a way to change output mode via redstone. Currently I believe redstone just shut it from taking items. I suggest to add a way to configure if it should stop it or change modes. For example through screwdriver.

What's the usecase for this? The batcher is designed to be configured once and integrated into setups.
This level of dynamic settings is a bit unprecedented.
