Hello Marty,
I'm not sure that we have the ability to capture the additional numbers that a customer would dial. I do know that once they have dialed the 10 digit number, you could capture their DTMF inputs and transfer them using a Transfer to Number action. I would recommend taking a look at this Resource Center article.
I'm curious if anyone else in the Community has any ideas on how this could be accomplished.
