Multiple heated chambers (printing + filament) – how to?

sorry as I'm new to this board, but I would like to ask a question. I would like to set a multiple (two) heated chambers on RepRap Firmware 3.x
I have nicely set main extruder heater, bed and chamber, but can't get another tool + thermistor paired together so I can use those for setting it as another “pseudo chamber” (it wouldn't be called via M141 obviously).
Problem is just that I can't get that second extruder paired with thermistor. Tool 1 doesn't have thermistor assigned and thermistor itself is showing in Extras.
I have Duet 2 Wifi + Duex5 for more heater and thermistor pins.

Please ignore thermistor type used, it's just for testing.
As I'm saying, topic might be called “Dual extruder and chamber” as I'm aware I can't use two chambers, but I would like to use another thermistor and heater output as an separate chambers for printing and filament heating chamber.
