Is there a way to do a save as for a GUI where you can save it as a completely different name with keeping the original file there?

I want to allow a user to save a GUI and name the file themselves. Just like a Microsoft office save as function, where they can save a document as another name but keep the original document as well.

Just leave the menu on the figure, which is already there by default, and the user should be able to do File/Save as.
