A Passthrough or Wait node simply says “don’t do anything that comes after this node until these two variables have values” - the two variables being passThrough and waitFor. So you could delete the current views and get the view names of the new views you’re going to create, but since you don’t want to create the new views until after the previous views are deleted you would want the new view creation to come after Passthrough.
Your waitFor input would likely be the new view names to be created. Those values wouldn’t get “passed through” the node until after the previous views have been deleted. Then you could continue to create new views with the new names.
