Is there a mod (or could I commission someone to create one) for the Sims 4 that adds a "Go Upstairs" interaction on stairs?

I'm a disabled gamer and this made the game so much easier for me in TS3, as I really like playing with the camera locked onto my sim. To move the camera up/down stairs and then have to lock the camera back onto my sim is very physically tiring for me to do.
