Allow wallboard for a project to also show plan branches

Currently if I want to have a wallboard for all plans and branches in a project, I need to load two separate Bamboo wallboard pages:

• telemetry.action?filter=project&projectKey=<key> for the non-branch plans in the project
• telemetry.action?planKey=<key2>&filter=showPlanAndBranches for the branch builds within a single plan

This is manageable for now with only a single plan containing branches, but it won't scale.

Is it possible to get a wallboard mode that combines the two? Perhaps with a branch icon indicator on the relevant builds, too.
