Multipose Script?

Hiya sorry if this is a repeated thread, have searched but am not having much luck.

Am trying to find a script that allows me to add multiple sit poses that I can then add to a sculptie piece of furnture so that when someone sits on it they can just scroll through the poses by clicking on the seat.

If anyone knows where or from who I can get something like this from I will be very very grateful!

I am used to building but dont have the faintest cvlue about scripting

Thanks in advance!
