Merge audience member email into attachment URLs

It would be great if attachment URLs and URLs in media descriptions let you merge in audience member data like name or email, the same way other links in the Hub do. We've had a couple times where we need to link to forms off of Searchie, and want to prefill the member data into the form. The only way to do this is to set up a separate transition page in Searchie, which isn't a great experience for the member (Having to click 3 links to get to what they want.)
