You may generate orgunits at any level on the fly by setting the map source
to "Database" as long as you have orgunit coordinates in your database.
There is now GUI for coordinate input in DHIS.

It is definitely possible and transparency is already an option when you

problem.

I agree with this, I think layer ordering is a must.
