Although not integrated as a slicer calibration, something like this already exists:

Yeah, I know, shamless self promotion. - But the included print profiles really make it easy and the lack of a slicer integrated calibration is exactly why I published it roughly a year ago…
What I recently found during calibrating all flushing combinations of two full AMS units:
- 9 out of 56 changes were off by more than 200mm³. (In BL’s defence, not all was Bambu filament - but even within those changes they were off in half of the cases…)
- 4 out of 56 changes were insufficient and needed more flushing
