This topic has been talked about a LOT! There was the concept of multi field and it just wasn’t practical. This however is a good way, I think, to do this.
Drive In: Drive into a field and if a field exists, it will open it. If more then one, a pick list for you to choose which one you want to open.
Save As: Just like every other Save As on any program. Save it as a new name and you have a copy. So simple - no more clone. Save as and go.
