2 sets of personality

[majid]

hi everyone

I m new to RDM, trying to design RDM-DMX LED fixture.
I have read old posts and found answers for most of my questions.

planning to make LED array fixture with 2 sets of personalities:
1: LED/pixel: {1 LED/pixel, 3/LED/pixel, ...}
2: Color: {RGB(3channel), RG(2ch), R(1ch) , ...}

seems it is not possible to have more than 1 set of personalities.
shall I do it using Manufacture specific PIDs?
or is there better approach ?
