Yes it is. And this is something that I wanted to discuss with Miika for a
while now (which is why I am now brutally moving this thread over to the
Subsurface mailing list):

How about we somehow shoe-horn the import of known data formats into our
download interface in a similar way? So that Ctrl-D gets you to a screen
that allows you to pick whatever dive computer you have, and then it
magically does the right thing? I.e., if you pick a dive computer where we
open files, we simply change the meaning of the device name text field
(just as we do for the Uemis).

This could of course be massively improved (it's a pretty old hack that I
did), but I think it's the right idea.
