As a product owner I want to group versions by name (across projects)

In the Plan view of the RapidBoard, I can currently see Versions in a column. These versions are grouped by Project, so if I have two versions with the same name in two different Jira projects, both are listed.

If my development project is split into several Jira Projects that share a common versioning scheme (i.e. they share the same version names), I would like to have an option to fold identically-named versions into a single version on that screen. Hence, I would be able to filter all issues belonging to a single (cross-project) version by clicking on that version name, and I would be able to assign an issue to a version by dropping it onto that version name, without having to look for the right version/project combination (GH already knows to which project my issue belongs).
