Access Saved MessageViewer Searches across namespaces

While the ability to save a MessageViewer Search in one namespace is helpful, it would be even better if we could access these saved searches to different namespaces. Right now the only way to do that is to open the Saved search in the namespace where it is saved and then change the namespace at the top to keep the criteria in context, then save the search in this new namespace. This is time-consuming. It would be convenient if we either we could save a search in a namespace that is accessible from any other namespace or be able to export the searches across namespaces.
