Using E1 for support interface layers only?

[numpad0 0]

My printer don't have the second extruder yet, but I'm wondering if it's possible to slice in Cura to use Extruder 1 for interface layers only.

 

The use case in my mind is PLA/ABS/common material on E0, and E1 would either use expensive filament such as water soluble PVC, or devices that don't actually print such as a felt pen on a solenoid or some frickin' lasers to process surfaces anyhow. End result is you get to print almost everything in same cheap materials but interface at top and bottom layers between the object and the support will be clean and easy to separate.

That is possible. You need to use the "Support interface extruder" setting for that.
