To add some historical context to this feature request, the exact multi-day scheduling logic we are talking about was actually an industry standard over a decade ago in Microsoft AutoRoute (known as Microsoft Streets & Trips in North America).
For those who remember using it, that software had a dedicated planning module that executed this flawlessly. You could set rigid travel parameters:
Start/End of Day: Defining that you start riding at 08:30 and must stop by 17:30.
Daily Driving Limits: Setting a maximum cap of saddle hours or kilometers per day.
Cadenced Breaks: Instructing the engine to automatically insert a 15-minute rest stop every 2 hours of driving.
Once you set these rules, the software would automatically slice a massive macro-route into manageable daily stages, placing overnight stop markers exactly where your time or distance limits were reached.
Modern cloud planners have evolved immensely in terms of maps, UI, and GPX track accuracy, but this specific logistical engine was somehow left behind. Reintroducing a modern version of that old Microsoft routing logic into MRA's multi-map environment would instantly make it the ultimate, unrivaled tool for anyone planning extensive tours. ️
