Hi Tegan,
I'm assuming some things about your situation here, but the first thing that comes to my mind is getting this supporting document into Laserfiche, generating pages, and taking note of the entry ID. You could then create a workflow with a Find Entry activity that points to this document using the entry ID, and then copies image pages from this supporting document to each new document that Quick Fields creates when Quick Fields saves the document in Laserfiche.
So, users would scan the document using Quick Fields, save it to Laserfiche, and a workflow starts (with starting conditions that only run this workflow when these specific documents are created in Laserfiche) that copies pages from the supporting document to the document from Quick Fields.
Does that sound like it might work in your situation? I'm not sure there's a great way for Quick Fields to find the supporting document in Laserfiche and append it to the documents in Quick Fields without sending the document to Laserfiche first, but there are plenty of people smarter than me here who might know a way.
