Compare Functionality Improvements

We use the 'Compare' functionality for version to version comparisons but this functionality is EXTREMELY limited.  We can only set up these 'compares' within a module view and need to re-publish to a dashboard every time we want to compare against a different version.  Please update this functionality to allow end users to use 'compare' on a dashboard!  

This is useful for all use cases and will dissuade people from using fake versions as they wouldn't have to use a 'lookup' to do version comparisons.  

Thanks.
