Turn off no longer used Hotend heaters during multicolor prints

[ChrisH2403]

Is your feature request related to a problem? Please describe.
In multi-tool prints, unused tools are often kept at temperature or at a cooldown temperature (e.g. 70 °C) until the end of the print.

This leads to:

• unnecessary power consumption
  

• increased thermal stress on hotends
  

• potential filament degradation in idle extruders
  

• unnecessary wear on your hotend fans as they spin at 20k rpm without beeing needed
  

Spare parts aren't yet reliably available as everything for the U1 can only be purchased as preorder and arrive maybe in May.

Describe the solution you'd like
Completely turn off no longer used hotends during multicolor prints.

Describe alternatives you've considered
I have written a post processing script in python which can be used in Snapmaker Orca as a postprocessing script but that requires exporting the gcode instead of sending it directly to the printer from within Snapmaker Orca as the Send to Printer and Print function completely ignores postprocessing scripts.

Additional context
I would like to see this as a checkbox in the "Multimaterial" Tab.
