After some researching on Cura and some fiddling around, I may have achieved what I wanted. This entailed creating copies of files, renaming the "aa" to "cc", and editing the AA to CC in the file There are 2 directories:
C:\Program Files\Ultimaker Cura 4.12.1\resources\quality\ultimaker_s5
C:\Program Files\Ultimaker Cura 4.12.1\resources\intent\ultimaker_s5
After doing this, when I change to the CC core for the material files that were copied and edited, Cura now gives me profile options and no longer gives incompatible messages. I did not get everything working as expected, but I am still tinkering. Once I get it all working, I will post the specifics.
