Anyway, one way to address your matter might be a folder rule on ACS side, which moves the entire folder to another location. A little script might be required for this, but nothing complicated. Straight out of my head...
- First, update via APS a custom property of the stored document in ACS.
- Second, define a rule on the root folder where all the "to-move" structures are in. Condition is "Items are updated" and do not forget "applies to subfolders", as the document might be in deeper folders. In Perform Action you select Execute Script.
Within the script, you need to grab the root folder and move them to the other location.
Does this make sense to you?
Alternatively you can also make use the REST Call task within the workflow and make use of the ACS REST API Explorer.
Hope this helps a bit.
