Agreed. Being able to put multiple trips onto the same map allows one to explore where they have been more explicitly. I sometimes do 4-5 trips per year, having a U.S. map show them all would be great.

That said, where on google can you already do this?

I would love to be able to show all the trips I took in a given year like you can do on Google Maps with layers. I road-trip a ton and use this as my primary planner. Being able to combine all my trips for a year or region would be cool so I don’t have to recreate on Google

I agree! I have multiple "basic" general trips and would love to pick and choose to a combined one.
