I am looking to merge pages of like documents and set the page number order.  

Example:  I have multiple documents that come into Laserfiche that pertain to the same shipment (Bill of Ladings).  The naming convention is #####-BL-# (12345-BL-1) and the 2nd page would come in as 12345-BL-2 and so on, this could happen up to 10 times.  

I am able to extract the BOL Number (12345) and then, I can also get the last digit (page number).  With the information I've extracted, I would like to place the documents in that particular order and merge 2-10 into page 1 IN ORDER.  

I am using the Move Pages activity in workflow, but it does not allow me to set where in the document I want the page to be moved.  I can enter a static page number, but that would require me to have a routing branch for each page number (2-10).  

Any ideas on how to achieve this without scripting?  Workflow and Move Pages configuration below:
