Add USERFILE to ARForm RDD?

I’m setting up a simple APR in E10 and we need to have the “reply to” set to the user running the routing’s email address. I don’t see the user email address in the available fields. Do I have to add the USERFILE table to the ARForm RDD? If so, what steps do I need to do?

(Also need to do the same on the CustSt and POForm).

Thank you.
