I have a scenario where a slight variant of an existing Blueprint would be the ideal solution.
Everything is in place with an existing Blueprint, however we have to give one device special permissions that we don't need for other devices.
However, there is no way to create a blue print based on one of our own existing blueprints.
The business case here is that we have to now double check that all the restrictions are identical between the existing and the new blueprint - that's a lot of work to double check that.
Templates are based on "industry templates". There doesn't seem to be a way where I can take an existing Blueprint and turn that into my own template.
