If i could put my graphics as a first layer and do the workshop, or sprints with attendees on a second layer would really improve the possibilities. 
As it is now I lock the graphics before the session. People contribute with sticky notes etc.

Suddenly where is a change of the original template that will help the workflow but then the challenge come. Unlocking, do the change and lock without messing up the contributed material.

Are MIRO planning layers?

cheers
