[Mailman-Users] Modifying Welcome Message Subject Lines

[Email Help]

I host several mailing lists off a single mailman server. I would like 
to be able to modify the subject line of the initial welcome message for 
some of the mailing lists. Is this possible?  I was able to modify the 
subject line of messages being posted by modifying the global pipeline, 
but did not see my welcome messages subject being changed.
