Is there anyway to create rules regarding the subject? I can't find anything in the documentation but if I could place rules looking for certain regex patterns that would be amazing.
I don't think you can enforce a naming pattern when people are creating the dashboards, but you could use the DomoStats datasets to check your names against a pattern. You could set an alert that sends you (or everyone, for some good public shaming) an email every time someone creates a new app/dash that violates your naming convention.
