"Save as" in route editor

When editing a route, I often forget to use the duplicate option before editing. Sometimes I just try to explore other route options and close the editor without saving after a few changes. But sometimes I make a lot of changes and want to save them as a new route, but there's no "Save As" option. I know my original route will be overwritten, but I'd like to have both so I have options while riding. Why isn't there a "Save As" option? Please add this.
