Is there any way to automatically add an attachment to a message in Mail?

Question

Hi,
I have to responsd to a lot of emails with basically the same response. I use a TextExpander snippet for the body of these messages. However, I usually need to attach a PDF file as well.
Is there anyway to automate attaching a PDF attachement to a message in Mail?
Perhaps, this can be done by adding the attachment into a Signature, although I havent seen a way to do this.
Or perhaps, some kind of Automator scritpt?
The mail account is actually a Google Apps account, so perhaps there is a way to have the GMail server do something to the message on the way out?
Thanks

it's fairly easy to create an outgoing message with attachments in applescript; just use a script like the following:
tell application "Mail"
          set newMess to make new outgoing message with properties {visible:true, subject:"test emal"}
          tell newMess
  make new attachment at end of attachments with properties {file name:"/path/to/attachment"}
          end tell
end tell
it's extremely difficult to add an attachment to an outgoing email that's already been created, however (there's no easy way in applescript to get a reference to an open outgoing message window if the script did not make the window itself).  I'm not sure which you had in mind.
