We have a couple of fields that we don't want to display on the form, but will be used by back-end administrators to add extra bits of data to those hidden fields. We need to be able to include the hidden fields' data in a confirmation email whenever those hidden fields are updated/edited by an admin.
How can we do this? In my testing so far, I don't see a way to accomplish this without making the fields visible, which we don't want to do.
