How do I copy a Web Mapping Application built using Map Series Builder?

[ARobinson]

I have created a Web Mapping Application using Map Series Builder. I would now like to make a copy (or even multiple copies) of the application, so that I can edit the copy to make a different version of the application. How can I do this?

For apps that I have created in WebAppBuilder, I can use the Save As option for creating a copy. However, for the app built in Map Series Builder, there is only a Save button, no Save As:

What can I do in this case to copy the app, please?
