Closest I've got is this: Driving Directions

But you're right. This could be an interesting idea for a future video. I'll add it to the list.

Richard Thanks....   I will try and build something and then perhaps share later....

I could not get this to work years ago with VBA due to the limitation with Google Maps in the URL string. I chose to export my list as a CSV and uploaded it to Google My Maps Dashboard as a new map. Even then, it limited each list to 2,000 locations. See Google My Maps. Maybe Richard has a great idea for this.

Mapsize.com lets you build a custom map with pins using addresses or GPS coordinates.  This is done with a couple of clicks through the website.  If you have GPS coordinates for each address, the website can pull that data from a file.  That might be an interesting place to start.

Mapize.com, I'll have to check that out. Thanks Matt .
