I have only tried this with 2017.
You can set up multiply synced data sets on your computers. To switch syncing on your mobile device you have to use the mobile devices menu to disconnect and then connect to one of the listed synced data sets in the normal way.

there's an existing ticket in our ticketing system with the suggestion to Permit iOS and Android app to sync to multple data files, so I've attached it to this discussion, this suggestion has been open for a while and I unfortunately have no input on the progress of it. Attaching the suggestion to multiple discussions will however increase the need for it to be considered on the developers review of suggestions.
