Verticale Tiles (two-active, all other passive)

Request:
When i do RDM stretch to two monitors it is possible to have 2 vertical
tiles besides each other.
But i have more i.e. 8 sessions open all and other current tabs/sessions are open and are active in vertical Tiles.
Now are all current active sessions in vertical Tiles and that isn't useable.

So i want only two Sessions(srv1+srv2) online/active in vertical tiles. And all the other
open sessions and aren’t visible,
The other 6 sessions(srv3 - srv8) are connected and open but passive.

See pdf-attachment for an example.
