Say you have a list of viewport-types (with different title looks). 1. How do you define which one is the default when adding a view to a sheet? 2. How do you get rid of one that are not being used and you no longer want in the list? Note, I ran the purge unused, and it only came up with a couple of the types I wanted to purge. I have gone through all conceivable sheets and made sure no viewport was using the types I want to get rid of.
