OpenAtlas

The old maps were set to show the layer with subunit polygons by default. This was highly desirable and helpful when putting in archaeological features such as graves. Now it is still possible to turn them on via going to layers in the map and turning them on - still easy enough. But would it be possible to turn them on by default, so I don't have to do it for every single feature I put into the database?
It would only be necessary for SiblingPolygons (and the plan but this is set to be shown on default already and works great).
