Currently it is not possible to exclude objects on a print containing multiple colors/materials. I wish for the ability to exclude objects on multi-color prints after the last filament change has been performed. My use of multi-color printing is mostly limited to text on the first couple layers and then a single color for the rest of the print.
I’m not sure what the limitations here are but i hope this can be made a reality considering the amount of material I can save by excluding just the one object that lifted from the bed or failed otherwise instead of cancelling the whole print or risking complete print failure.
