When using Mercurial linking, is it possible to add a feature to allow you to mark renamed object (in particular sprocs, views, udfs), so that the change history remains?

At the moment I am forced to use "Working Directory" so that I can save the changes and tell Mercurial that the object has been renamed.

Using the Mercurial link results in an added file and a deleted file and a lost of change history.

I realise there is already a completed feature for the renaming of tables to stop data loss, which can now be done with the Migrations (http://redgate.uservoice.com/forums/39019-sql-source-control/suggestions/867961-treat-renames-as-renames-instead-of-a-drop-and-an), but this is not about data loss, it's about development history loss.
