Multi Instrument Staves

As I understand it from reading forum posts, Dorico will eventually have full support of having multiple players on the same staff.

When this is added, will it be possible to have two different types of instruments on the same staff? Many works will have Trombone 3 or a Bass Trombone on the same staff as the Tuba.

Also, will it be possible to switch mid-flow whether or not players are combined and how they are combined? Some works, such as the Rite of Spring often switch how players are arranged on staves, depending on what each player is doing.

Edit: The second excerpt from the image actually happens first.
