2619 layout

We are first time RVers, new to this Forum, and are considering purchasing a new TM. We like the 2619 for many things and especially the ability to store in our garage. With just 2 of us, we really prefer a sofabed instead of the dinette and second double bed. Does anyone have insight into whether TM would consider making it that way instead of with the dinette and second double bed? Thanks.
