Allow for dynamic URLs in Embed block using fields from a single record

This would be HUGELY helpful. An example scenario is this. You have a list of clients in a table, complete with email addresses. When you select a particular client, that email address is fed into the Embed block URL which happens to be a Gmail search for that particular address, effectively showing you message history for that client. Allowing for dynamic URLs to be used for the Embed block in this way would be fantastic & could have so many other uses!
