Adapting "Print MultiEnvelope from E in W" script

Title: Adapting "Print MultiEnvelope from E in W" script

How can I adapt the script “Print MultiEnvelope from E in W” for  printing on stationary with pre-printed  return addresses?  Or where can I find such a script?

Help! . . . I’m also looking for a way to use Entourage category sorts in the data merge manager.
