Unfortunately, it’s not possible. The scenes folder location can be configured only by modifying the configuration file, there is not UI for that, and only one scenes folder is supported.
I see. We’ll help you to edit the configuration file to point to another directory. Please send us (support@shapespark.com) the config.json file from C:\Users\AppData\<YOUR-USER>\Roaming\Shapespark and the new scenes folder location.
