Feature request: punching -in TransactionID on a PDF to validate signature when printed

Dear Adobe Sign,

Feature 1. Could you add an option to punch-in document's TransactionID below signer's signature and date, so that people who get only the printed version can validate the signature with punched-in TransactionID (on a no-account-required Signature Validation page)?

Feature 2. Also, currently, when i click on a "Validate All Signatures" link in a signed pdf it sends me to a page that just says is the TransactionID valid or not, but does not confirm signer's identity with his/her e-mail or in any other way. Could some non-repudiation feature like that be added?
