Possible to add height modifier to modify speed automatically?
I've been printing some cookie cutters and have been experiencing issues because the bottom (handle) of the cutter has a fillet and is rounded on both the inside and the outside.
I just added a height modifier using this guide: https://help.prusa3d.com/en/article/modifiers_1767/ . It seems to be working wonderfully! I brought the speed down on only the perimeters for the first 4 layers and the filament is now making contact with the edges because the speed was brought down. Really happy with the results.
Is it possible to save/add this height modifier somehow so when I import new STLs into PrusaSlicer, it automatically adds the modifier to the print? This would save a lot of time because ideally I'd want to add this modifier to every print going forward.
Thank you!

You can save it as a project (3mf-file).

Thanks for the suggestion. I tried that, but I think it still keeps the same STL file in the project. I'd like to automatically apply the height modifier when I insert a new STL.
Probably not possible, but worth a shot to ask anyway :).

Are all your cookie cutters the same height? If so, you could add some custom gcode to vary the feed rate at the top layers. Something like:
M220 S{if layer_z < 20}100{else}90{endif} ; M220 adjusts feed rates
inserted under Printer Settings->Custom G-Code->Before layer change g-code (adjust for desired height) should work. This will be applied to ALL prints done using this customized printer profile. Alternately, you can insert custom gcode at a specific height, so something like:
M220 S90
at the desired layer would work. Slice your print and in preview mode, adjust the slider at right to the desired layer, and right-click the little plus sign (+) to select Add custom gcode.
