RLS - Dynamic Distribution List

It seems that Dynamic Distribution Lists from AD are not supported with RLS in the Service. With Dynamic RLS built into the report we are looking to add one or only a few dynamic groups to the role in the service to make the distribution of the dashboards/reports as simple as possible. Standard Distribution Lists where the users are specified in the group in AD seem to work OK but not Dynamic ones. Is this on the roadmap (or of course, have I missed something!)?
