Mega Sign to many followed with another signature?

Please help. We must send 25 contracts today using Mega Sign. Final signatures must be added by a manager and attorney. How can we accomplish this, so after each on the CSV sign, each get routed to two additional signers? I have spend a lot of time searching for an answer. I see others have asked, and see some references to a planned "Giga Sign".

THANK YOU SO MUCH!
