Apply background map to all panels in a grouped grid?

Question

In Graph Builder I often create grids of maps using latitude and longitude data. For example, I might plot flight time histories where:

* Airline is placed in the Group X drop zone
* Flight Index is placed in the Group Y drop zone
* Longitude is placed in the X drop zone
* Latitude is placed in the Y drop zone

This produces a grid of small maps, one per airline/flight combination.

The issue I run into is that I sometimes forget to set the background map before building the graph. When that happens, if I right click a subplot and set the background map, it only applies to that one panel, not the entire grid.

I have tried a number of things to apply the map to all subplots after the graph is already created, but so far I have not found a way to do it.

Is there a way to apply or change the background map for all subplots in the Graph Builder grid at once, after the graph has already been created?

I don't know if this will work, but have you tried holding down the CNTL key as you set the background map?

Broadcasting (holding ctrl) did seem to work with background maps.

If you happen to make the "mistake" and have the map only in one frame box like this

you can:

* Right click on the frame with the map Edit > Copy Customizations
* WHILE HOLDING CTRL right click on one of the other frames Edit > Paste Customizations
