2) can be done. You can use Set variable to compute the file path and name of your snap shot link. Then the script step Save Records as Snap Shot Link with this same variable creates the snap shot link and you then turn around and use the same variable to refer to the snap shot link in send mail to specify an attachment for the email.
That's a good idea. Thanks.
I could continually save the file using the same name and attach the (most recent) version to the email.
