Export to Second Destination/Folder

In my previous experience with RW, I could create multiple destinations/folders for exporting a project - one for Production, one for testing, one for initial development, etc. as needed. This allowed me to test new designs without impacting my production site.
The only way it seems to be possible in Blocs is to duplicate a project and then create that second (third…) export location. Then I would have to re-duplicate the project to get it to production. Note that I put all my assets in a folder on the production site so I don’t have to worry about those.
Is there another way to work this or is this something for @Norm to implement?
Thanks in advance,
Fred
