Alias teammate email addresses in rule-set CSV file upload to Teammates in Front

When you so a CSV file up-load into a rule-set table, email addresses don't link to Teammates in Front like they do when you do a CSV file upload for Accounts/Contacts. If a customer wants to use Inbox, Tags, or Teammates in a rule-set but has a lot of rows and wants to use a CSV file upload, they need the IDs of the objects instead of names or email addresses. Ideally, it would be cool to be able to alias at least email addresses of Front teamamates into Front Teammate objects like we do for Account/Contact CSV file upload.
