Suggestion: expose group details e.g. so we can calculate total size of group artifacts

Problem

After uploading a build, I am trying to calculate the total size of all the artifacts that belong to a specific group so that I can report the total size in the status we post to the commit on GitHub. E.g. here there is a group called "core":

Currently we display the total size of all artifacts in the build but we want to change this to display the total size of all artifacts in the "core" group.

I tried to do this using the public properties in types like Build however it seems the group details are not exposed.

Proposed solution

Could we add a groups property to Build?
