It reads the document, and finds the "client name"
It uses the "Sort into subfolder" action to create a folder with the client's name, and moves the document into that sub-folder.
Here is a photo of the rule:

So far the rule works fine.
However I would like that newly created folder to be located on a different drive.
I thought about using the "move" action, to move the newly created folder but I think that it would wipe out any existing folder with the same name each time another document for the same client appeared.
Is it possible to create a drive/folder/file path before the final destination name? Or can you suggest a work-around?
