If you are referring to the standalone version of the app, then no. There isn’t a way to do that. I don’t have any immediate plans to do that, since it requires a lot of basic infrastructure to be created first that’s not present in the app (because the app browses “real” files and as such it doesn’t have the ability to browse “fake” files.
Photos itself has that ability, so if you are using the extension, you can duplicate the image and work with that.
