Michael,
This sounds like a great feature request you should post. The only "workaround" you might be able to do (not ideal) would be to create a 'Survey' that only had the outbound email and no links or anything else. Once you get all of the clients in the same view, you could send the new 'survey' to them all at once.
Anyone else have a great idea until this feature is added? I have been thinking of this as well...
