Github integration for subitems

The new Github plugin is simply awesome, if it could work to link to sub items then this would make it simply excellent! We have many cases that a single item will require changes across multiple repositories. In that case we want to create subitems for each repository that we are applying the change to. It would be great to be able to link subitems to GitHub by referencing the subitem id

I completely agree with this. This was the very first thing I wanted to do with the integration and could only get a PR to link to the Project and not the Sub Item.

This would really enhance the way we work if it were possible to link the Sub Item to a pull request as you may well have many Pull requests that relate to a project.
