Create "Master Route" For Multiday Trips

I would love to be able to take more than 2 routes and join them all together with 1 click instead of having to go through and join 2 at a time multiple times.

For multi-day trips, I create a folder and create routes for every single day. I then like to have 1 "master route" to see the total details for the entire trip. But if my trip is more than 2 days, then I have to join the first 2 days, then repeat the process for every additional day of the trip.

My workflow includes creating the original routes, then duplicating all the routes to join them to each other (because joining seems to not create copies, so I don't want to lose the routes for each day). Then after duplication, I go through and join 2 routes at a time.

It would be way easier to check all routes and have a button that either copy and joins all routes, or a create master route button.
