I am trying to create a custom button at the bottom of a resource that will save the record and then take all of the information in that record and duplicate it into another record. This duplicated/copied information would then give the user a jumpstart to enter another record. Right now the only actions on the Create and Update pages are Create/Update, Create/Update and Add Another but those two buttons don’t fit all circumstances. And the last option just provides a blank form. I want the previously entered information to be auto-added to the form to save time.

Can somebody help me figure out a way to add additional buttons to the forms so that I can extend the create and update functionality?
