P: Display the panels associated with the selected mode on the secondary display

I use the secondary display feature a lot, often in either Grid or Loupe mode. It's a great productivity tool. What I'd really like is to be able to view the panels associated with the mode of the secondary display. Let's say I'm in Map or Book mode on the primary display and I'm using the secondary display in Grid mode. I realise I need to fix the metadata. I have the Grid display on the secondary monitor but there are no panels. To fix the metadata I switch the primary display back to Grid and edit the metadata. What I want to do is just fix it in the metadata panel next to the Grid display on the Secondary window.
