Automation Required for 'when all Items & Sub-Items are marked as DONE, move the entire board to a sub-folder in the same workspace'

As the title suggest, I am after a automation (which I’ve been advised is not currently available) to Move a board to a sub-folder within the same workspace when all Items and sub-items of a board are marked as done.

Example is that we have our workspace broken down in ACTIVE Projects and COMPLETED Projects - by use of Folders (on the left side pane).
We want to automate the moving of a board from ACTIVE to COMPLETED when all tasks are DONE

We’re new to MONDAY and liking it so far.

Support have suggested I post a topic here to see if anyone has a workaround or MONDAY Devs see this to hopefully release this automation in future releases.
