eTransmit for Revit is a great tools, and with one minor tweak could be made even better.
When selecting "Upgrade and Cleanup", there should be an option to select specific sheets to include / retain.
This is especially useful when you have a starting view (created as a sheet) which contains a legal disclaimer. This obviously needs to be kept in the file when issued, not removed. Hence why deleting ALL sheets becomes an issue.
Please consider.....
