In my past experience working in branches, if a CSR knows that something is not going to be reviewed or sent down for imaging, they will half [censored] it. If you can make it part of required fields in the software you are using, that would ensure they fill it in. Otherwise I would suggest having a checklist they fill in by hand or on computer. When Management reviews signature card for account, they also review checklist.
All depends on your account opening process, who reviews signatures cards, how you image your documents.
Hopefully helped you a little bit or gave you some ideas, have a great thanksgiving
