How to manage Lab Interface Results When A Provider Leaves

Hi all
I am curious how others manage shutting down lab results for providers who have left the practice.
When we terminate provider in eCW we are able to take steps to immediately stop them from receiving surescripts requests, i.e. med refills, however we seem to have to wait for our lab partner (quest) to take action in their system to prevent existing / new lab results from coming back. Does anyone know if there is a way in ecw to shut down receipt of lab results after a provider leaves?
thank you
