Lean Tagging - Data Table Export Functionality

It would be useful to have an option to be able to export the Lean Tags table (in our case Requirements tags) for the ability to gather data on processes missing tags . Can see there is a report called Requirements Mapping but it only provides details on processes containing tags as opposed to ones which havent . We have a need to identify where there are gaps / tags missing . Having a flat export would provide a base for this data .
