Final signer(s)
In many agreements the places that signers sign is different than where the counter signers sign. This isn't an issue when the number of signers is known when creating a document, but if the document is designed for a variable number of signers then it becomes problematic to get the final signature in the correct location. It would be nice to be able to specify a final or sender as the participant on a signature block then the last participant or the sender would sign in a specific location.
