So I know I can remove an object interaction through Returner by setting it to User Directed only but that seems to affect all objects of that kind (all stereos in this case).

What I want to do is stop my Sims using a specific kind of Stereo to work out so I can essentially have a dedicated workout room as they would only be able to do the work out interactions on one kind of stereo. Is it possible to make only the 'BeoWuuf Stack' have the work out interactions set to autonomous and the other stereo kinds disabled?

Thanks in advance

I don't think so.
