@Tony_U The way that I plan a route is to make everything into one great big route and use a start time for the first waypoint.
After guessing how long that I expect to be stopping at various points, this can be done with the Insert Pause feature I then roughly know when I am going to stop and plan accordingly.
Now if you look in the Toolkit, you will see a Split feature, using this will split off a portion of your route which can be renamed. I tend to use something like "Sweden 01" so the subsequent days follow in order.
Then reassign a new start time for the first waypoint (your last one from the previous day) with a new start time.
