You can sort of do this in Google Maps now, though it's probably not quite as automatic as you might like.
Consider this 26 hour drive from Bangor, ME to Miami, FL:
To add a waypoint, I'm going to click the ā, and then drag the new waypoint to the center of the list:
Then I click in the text field, and either type in a city or click on the map. Here, I will guess the halfway point and type in Richmond, VA and press Enter. I first thought of Washington, but it's probably the sort of big city you'd rather drive through than stop in. I end up with this three point set of directions:
Here, if I click Details, it will show me separate travel times for each segment.
Once you have a waypoint, you can drag it around to change your route, and click Details again to see the new travel routes and times.
It's not perfect, but perhaps it's good enough?

Also maybe not a perfect solution for your usecase, but maybe better than Google Maps: https://roadtrippers.com/ This allows you to create a route and add intermediate stops on an interactive map. The downside is (since that tool is mainly targeting sightseeing road trips), that you have to select POIs for your stops, like restaurants, hotels etc. You cannot just put a marker on any arbitrary location. But it at least shows directly the times and distances for each sub segment in the trip overview.
Another tool which i used to plan my last roadtrip: https://trips.furkot.com/
It can split the tour into daily chunks, with suggestions where to stay overnight so that it fits the plan etc.
