Editing system filament presets is a PITA
So the shrinkage compensation system preset of 0.18% for Prusament PC Blend is off enough that my parts are not accurate. I can change this of course but then I have to save this as a user preset. This is super annoying because I have to save one for each nozzle type since the max volumetric flows will be different. I can edit the appropriate section (which was hard to find) in cache/PrusaResearch.ini but that will get overwritten on the next update. Wish there was a better way to overlay user specific changes on top of system presets without having to save it as a new instance. Hopefully this gets fixed in PrusaSlicer 3.0.
This is also a reason why one shouldn't blindly trust the Prusa supplied presets.
