I am sorry, but as i said i cannot create fixtures files for modes using subfixtures as it's not compatible with cuety.
The trick you can use is to find fixtures in the library ( first have a look at the generic manufacturer) to find fixtures with dmx traits which would fit each subfixture dmx traits
for the strobe part of the fixture patch a generic strobe with DImmer and strobe channels and for the RGB part patch a generic RGB PAR "DSRGB".
Strobe part address : n
RGB part address: n+2
I hope this will help you.
