Is it possible to do this?

Hello,
I’m trying to come back to Dorico since the update 1.1.
Is it possible now to do this: switch from two staves to one stave (and vice -versa)?

Finally found an approach to do this but not at 100%:
I can’t found how to change the allignement (vertical) when we change instruments fron two to one stave or one to two staves.

Based on the limited numbers of published scores in which we can find examples of players switching from one staff to two or vice versa within the same system, we decided to centre the staves relative to each other. We could potentially add an option to allow the single staff to be aligned with the top staff of the two-staff instrument in the future.
