During upload to the browser interface, if I upload an updated version of a previously uploaded folder structure, the app asks me if I want to replace the previous folders of the same name, if I want to skip folders of the same name, or if I want to keep both.
I propose a fourth option of merging folders of similar names and then if this choise is made, ask for the choice of replace, keep both or do nothing for files specifically. This behavior would be similar to the experience of moving or copying files in folders on Windows.

This feature is critical as there is no app for linux yet, leaving us to use the browser interface.
