Custom Stamp Help

Hi there,
I've successfully set up a dynamic stamp that automatically inserts the current date into the field, but I also need one that allows the date to be input manually, but I can't figure out how to get it to carry over to the finalized stamp.

Stamp 1 is the successful dynamic stamp.

Stamp 2 is the stamp I am trying to create.

I've editeded stamp 2 to include a text field and date format and saved it, but when I go to use it, there is no field to type in the date.

Is there some kind of script I need to enter for the date form field to carry over to the final stamp? If so, what would it be?

Thanks!
