Feature request : Filament detection sensor per toolhead

[orotecluc]

In my setup for ToolChanger, I am planninng on :

• either have an extrernal filamentsensor (type BTT motion sensor or so) )per toolhead just before the entry of filamnet, and connected to my MainBoard
• Or have a filaments sensor switch just at entry of extruder (like they have done with the ERFC2 project), and thus have a microswitch wil ball installed into the extruder housing, and connected to the EBB

So ideal, we would have to be able to assign any tipe of filament sensor (by name) to any tool(by Id)

I am not sure if this is feasible
