Multi-rider mount help?

[CaffeinatedMayhem]

Is there any addon that moves the 'Mount up" for the second person to a keybind or synergy (off the wheel interact)

I have a directionally challenged friend I'm helping quest for the 10 year skin, but they get frustrated every time we mount up on the multi-rider.

Is there even a hook in the API for this?

Thanks!
