Hey @shiretrib,
You’re correct, there’s no option to save a specific request into a workspace when trying to duplicate or save. These actions are limited to the workspace you’re working in.
However, you can share (or duplicate) the collection (which contains the request you want to move) to another workspace. Here’s more info on sharing collections- https://learning.getpostman.com/docs/postman/collections/sharing-collections/.
Hope this helps!
Cheers,
