Zebrasub generation (18+)

I have noticed that no matter what i do with Pony XL and AutismMix. When i try to pair a pony with a zebra, it will ALWAYS generate the zebra as the dominant partner. Even though i am trying to generate images where a zebra is a sub, it never works. Any ideas how i could actualy generate zebrasub?

little late but you can try to define the zebra as pony. feral pony, red stallion, zebra pony, prone bone, from side, horsecock
That and you can brute force it with a regional prompter to define each section separately.
