I am still waiting on an answer on this as well. I believe it requires a python script. The last part of your question though is achievable with a view schedule. (although I am not sure what you mean by partially loaded view templates. Do you mean which items aren’t included in the template?). If you still want to include that in your dynamo script, This section talks shows a solution for selecting all view templates Delete view templates not in use
There is probably a way to get which view is applied with some edits to this script, but This is as far as I have gotten so far.
