Exclusion List for Blocking Mode

[SonOfTheStars]

Hi,
Ive been playing around a lot with crafting managers lately and I noticed that in some instances I do want blocking crafting mode enabled on them, but have an item like a programmed circuit, mold or extruder shape that I need for the machine to run.

Would it be possible to give the Blocking upgrade Tab a list of maybe 1-3 items that it will ignore? A sort of exclusion list for the blocking?

for machines that have recipe use 1 slot, turn off the blocking mode
other solution: make other machine or get other Crafting Manager without Blocking mode

This is not a real solution to the problem, thats just a workaround. I specifically want blocking mode in some GT machines that need programmed circuits in them.
It should be possible to give a 1-3 Item exclusion list to the blocking mode so you don't have to make extra machines as a workaround for this.
