I don't think so. As far as I am aware, has to be one who can give the other instructor ratings (C, B etc)
You could try some of the part timers (if they're still testing) e.g PO, DH etc. I did mine with GG who I dont think is testing much anymore but still in the game somewhere ?
Where abouts are you doing it ?
I found it a pain with flight schools as they had never done any so no idea really what to teach me. Lucky I found someone privately who had put a few people through the D cat so it all worked out well
