Link to aggregate graphs

We have a very large installation of observium.  Within our infrastructure we have key components that use physical ports spread across multiple devices (ISP's).  To calculate the total consumed bandwidth we use the aggregate graph feature (no problem).  However we are trying to create a custom high level dashboard view using a separate html page.  We can link to individual graphs however we have not been able to find out how to link to aggregate graphs.  Would this be something easy to add?
