Adding a signer after starting a document-very inconvenient and time consuming

It is very inconvenient that we are unable to go back and add an additional signer after starting a document, but before clicking send.  We have forms that include about 6 signers that each need to sign at 2-3 times on the document.  If we forget one person, we have to start the entire process over.  It is extremely time consuming to place all of the signatures correctly and it happens often that we need to add another signer.

I really hope that this can be changed at some point!  If there is someone else I can contact, please let me know.
