Dual EASA SFI ratings

[oldpaint]

Hi...
Can someone direct me to EASA regulation regarding having dual SFI rating?

Such as having simultaneous A320 and ATR Synthetic Flight Instructor ratings.

I can't seem to find any EASA reference regarding that.

Thank you very much for your help.

It's all in cap804. If you're an SFI, you can add another type by completing the simulator content of the TR course and teaching 3 hours of a TR to the satisfaction of an SFE.
