Template caching tag storage options I can see that normal caching can have it's storage specified, but I would specifically like to be able to set the caching storage method for the template tag {% cache %}.

At the moment it appears to be hitting our MySQL database very hard and so I would like to consider using something like Redis instead.
Currently, the template {% cache %} tag can only cache to the database. 

See Brandon's comment here ("Template caches always go to the database").
