This is not usable at the moment as the backend requires even
more details, such as binning parameters, which this dialogue
does not provide.
It might be a matter of relaxing the rules on the backend or,
perhaps more likely, rethinking the project creation / editing
frontend. Maybe refactoring the frontend so that saves are done
in one go for the whole configuration as opposed to piecemeal as
currently done might make it easier to work on a configuration
(especially a new one) fully offline.
