The current design supports either way of doing this.
You come back from your dive. 44 dives on the same dive site. You let your
phone run the whole time. You will likely have 44 fixes. Now you can load
the gps fixes first. When you go to edit your location you will see the
other fixes that are close by in the marble window (many with the
auto-generated title) and you can see locations with the same name (or
start of name) in the completion drop down.
And if you enter names first you won't get help from the globe (as that
doesn't know where you are), but you still get the auto completion (either
once you entered the first dive or right from the start if you have been
here before. And in the latter case you can decide if you want to reuse
the old fix or later add a new fix from your phone.

I want as little required interaction on the companion app as possible.
Maybe that's because I get viciously sea sick and staring on a little
screen on a boat is just a horrible idea to me. So the idea of just
having it running in the background and then matching the gps fixes with
dive times very much matches my usage pattern.
The names that come from the companion app are made unique by Subsurface.
And the decision when two fixes that are XX meters apart are the same site
or a different site is not something that I really want to hard code in
either of the two apps.
