Taskboards across projects

I was happy to find customization capabilities so that I could define a context that filtered down to just issue assigned to me . It is a convenient view for work planning and status. However, quite a few of our developers work on more than one project including (and especially) me! We also have some project managers that manage a few related projects in concert. Could there be a way to have related projects in one taskboard? A manager could get a multi-project taskboard and developers could define a context for only their items across related projects.
