I have used other esignature systems that allow the signer to attach documents to the file when they sign them. I.e., I use the system to process new students into a EMS education program, during our onboarding process I used adobe Esign to allow them to sign their student documents remotely and electronically preventing them getting lost. However, part of the application process is that I also must have copies of their drivers license, vaccine records, etc. So creating a way to have them "submit" these documents with the document they are signing with AdobeSign would keep everything together and organized.
