In short, no.

If you were to go directly to a few different federal legislator's webforms you would see that not every legislator's webform is the same.  In order for the Convio webform Action Alerts to work with every legislator, the alerts have every field that is necessary to submit every federal legislator's webform and we have configured the fields so that they will work on every alert.  Basically, we have configured the alerts to work with the lowest common denominator.  That is why the "Title" field is required, for example.  It is also why the options available in the "Title" field cannot be customized to include other titles.  If we were to include other titles, there would be legistavie webforms that would not accepts the alerts submitted and thus fail.
