Deleting Sign Request before Sending

Hello,

I have several sign requests that were created, and had either subsequently found errors within the document or inadvertently added an incorrect email address.

As it stands now, there is no way to delete the sign request without first sending it and then cancelling it. There is also no way to add, remove, or change recipient emails once the document has been sent for sign request.

Is there a way to incorporate these options?

Thanks

Jon
