Party's seat assignments

I posted this in another forum a few weeks ago, but no one knew what I was talking about.

I recently came back to Party (after I learned to play poker a bit better), but I could have sworn that there used to be an option where you could sit in the same chair all the time. The table would rotate around, so that your spot would never change (similiar to UB). I can't seem to find it any more, but I suppose I could be confusing poker sites, and that this feature never existed on Party. Or did it, and now it's gone?

Thanks.
