Sitable Tammed Entity

Greetings!

I need help making a tammed entity that works just like the tammed wolf in the actual game, I wanted it to sit down when the player right clicks on the entity, and get up when the player interacts again, basically making the tammed entity to stop following the player while sat, and of course not move or anything, just staying there.

I looked up and didn't found anyone asking or talking about it, so I'm trying my luck.

(I'm making a cube-like entity, I wanted it to not move the whole time, tammed or not, but when tammed, follow the player, and only him, but MCreator limited the movement choices...)
