Data classification for dashboards locks reports to default

I thought I would share the workaround that I've come up with.  Since reports are automatically assigned the default classification, I've unchecked the "Show Tag" option for the default classification, and then relabeled all the dashboards with a second classification tag that is set to display. 
It certainly isn't ideal, and doesn't allow for brand new dashboards created by personal users to have an automatic tag explaining what audience the contained data is appropriate for.  It requires a "no tag, no sharing" approach to dashboard development, which is easier to forget than seeing a tag marked "PRIV" for company proprietary and private data.  If anyone else has a solution to either change tags on reports (or a better way to remove them from reports without removing the default tag on dashboards), please jump in.
