their accounts are all local to each server, rather than user accounts existing separately and having access granted to them, so I’d say no but I’ve never tried.

It would be up to the client app to log into multiple servers and I don’t think any of them do that without having to log out and switch servers then log in again, as opposed to plex where you can have one user logged in and pin libraries from multiple servers if needed.

Thats one of the things I wish JF did better but it's getting there slowly.
