I further experiment it.

I observed that I can save 12 independent registration settings (A-C)*(1-4).

And I can assign it indecently manually to any custom style that I have selected.

I also observed that when MSA in on (MSA panel memory) it is only retrieving the registration from panel memory A.

Can the resister setting for each style be embedded in the custom style when saving?

Thanks,
Doron
