Single webform but different document is chosen based on how a user responds to a dropdown item.

Hello, I have a web form that I have created to facilitate the filling out of a pdf form.  However I am wanting to add a drop down entry of two possible chooses.  The first choice option means that the user would continue filling out the current form.  The second option would divert the user to filling out a separate pdf form.  The questions that correspond to filling out the form are going to be the same.  The only difference is the second option will have one different signer of the form than the other option.  Do you think this functionality is possible?  Or would I need to create a separate webform and link the other pdf to that form?  Also what is Maestro?  Is that something that would allow more customization than what is offered in the main docusign website?

Thanks,
