Usually I just go for the overall sorting, and use that everywhere, so each doctor record gets a Position field I number them 10 20 30, etc, and that will be used everywhere the team is listed. This works 99% of the time.
If you need different per-unit ranking, the easiest way is to reverse your ref connection. I’m guessing you have a multiref from Doctor to Unit? You’d rebuild that as a multiref from Unit to Doctor.
This way;
Each unit knows what doctors work there
And exactly what order they should be presented in
The doctors page can also drop a collection list to Units, filtered to “where doctors includes this doctor”, to get the unit list and avoid duplicate data admin.
You’ll probably want a sort order on your Units as well, so that the bigger units are sorted first- or else just go with alphabetic.
