Hi Liza,

I've had some success in doing this. What I usually do is assign the submission ID to a field value on each document you're saving to the repository - the form itself and any uploads. Then have a workflow configured to act on the uploads when they're submitted. The workflow would look for the form with the same submission ID, move pages from the upload document to the form document, and delete the upload document when done. 

This will require your upload fields to only accept files that be turned into Laserfiche pages. The repository profile you use to save the documents into the repository must be configured to generate pages on PDFs if users will be uploading PDFs, otherwise pages won't get generated and you subsequently won't be able to move them to the form document.

I see in your screenshot you have a Word doc that you want to merge with the form - I don't think that's possible with out-of-the-box tools. If that was a PDF instead of a Word doc, I think you could get this done using Workflow. You could still use the submission ID to find and link the documents together, but you won't be able to merge them if the documents aren't composed of Laserfiche pages.
