I have not tested this outside of comparing the gcode between SuperSlicer and Cura. Values were within 1mm of of each corresponding value.
I don't know python and have no interest in learning it, hopefully someone can clean this up.
START_PRINT BED_TEMP={material_bed_temperature_layer_0} EXTRUDER_TEMP={material_print_temperature_layer_0} AREA_START_X=%MINX% AREA_START_Y=%MINY% AREA_END_X=%MAXX% AREA_END_Y=%MAXY%
On MacOS with Cura 5.0, the path to the scripts folder is
/Applications/Ultimaker-Cura.app/Contents/MacOS/share/cura/plugins/PostProcessingPlugin/scripts/
(You may need to right-click on the Cura app and click "Show Package Contents" if you're navigating with Finder)
