Hi burljohnson
We are in a similar situation. As an OEM we also give our customers designer licenses. We do have a different approach. We have a group called Designers. Users in that group have access to specific dashboards, such as Datamodel, User/Group Creation/Edit and the folder Templates. In here are we have dashboard templates they can use. They are shared with them and if they want they can duplicate and use them.
You could also export your dashboards to .dash-files and place them in the resource-folder. That way you can create a downloadable link that you can place in a Blox for users to download
