Allow External Data User Content in Dashboards to be password-protected

Right now we have the ability to push a CSV, XML, HTML, RSS, or Image file be pushed into SiteCatalyst Dashboards.  Unfortunately, the data contained in these types of reports is always Private.  Companies very rarely are okay with sharing the data contained within these external reports.

The User Content external data in Dashboards should be enhanced to allow password-protected data to be included.  This way my data is secure and available to the dashboard.
