Two Users with One Apple TV

My wife and I each have separate trainers and we do NOT ride at the same time. We each have our own Zwift accounts. Is there any way to avoid selecting our trainers when logging into Zwift? I mean, after logging into Zwift we would prefer to not then choose which trainer to use, to have Zwift know to always use one trainer for me and the other for my wife. Is that possible? Thanks.
