MS Team w/multiple Channels each with their own Planner

I'm using a Microsoft Team to manage the department's projects.  This single "project" Team has multiple Channels; one Channel per project with each Channels having its own Planner.  Is there a way to roll these individual Planners into one master Planner for an executive to view all in one Planner?   

Options that I've considered...

• Using the one MS "project" Team with one Planner, each project running on one Planner card. 
• Exporting each Planner info and then seeing if I can build import into another application (i.e., MS Project, or a separate Planner)? (seems like a lot of work)
• Each project having it's own Team, does give more permissioning abilities, but doesn't solve the multiple Planner problem.
