Hi, Dennis, welcome back. 
The challenge with the solution you provided is it relies on the user to take some action. The END_SQL parameter was added so that folks could include special database instructions like “for uncommitted read” and so on, but it works perfectly for adding comments to the SQL as well. By setting it as a universe parameter, it’s going to be automatic on every query, including adhoc.
