How to select default 3D layer?

I’m forcing myself to move from doing everything on one single layer to less destructive workflow.
So I made base sculpt and created 2 layers for details. Then I want to add changes to base layer, but it won’t let me until I hide both layers I created.

How should I go around that? I really need to see changes from those custom layers for proper adjustments of base layer.

you can just add another layer to make the changes you want for base layer. duplicate the subtool then hide your other layers you don’t want on base layer and bake the layers down.
now with the duplicated subtool, add a layer. then on original subtool, turn on the additional detail layer and project it onto the duplicated one, etc.

hope it makes sense

Thank you.
