[FEAT] Overshoot optimization

[henning-schild]

Is your feature request related to a problem? Please describe.
Prices offen largely differ when choosing a destination which you do not even care about, or a departure station which you do not plan to use. i.e. you overshoot a trip from "Dresden Hauptbahnhof" to "Frankfurt Main" by choosing "Bruxelles Nord" as made up destination, you will get a chance to ride the whole middle as "Europaspezial" not even going to Belgium but to Frankfurt only

like 10 years ago that worked like a charm, done manually at the time (29 EUR Europaspezial vs 120 EUR or so)

Describe the solution you'd like
Prefixing/suffixing unneeded legs, maybe especially to other countries, and see what that does to the price.

Describe alternatives you've considered
An alternative to reach discounts "abusing" neighboring countries without visiting, book on their sites. Booking from CZ when actually coming from Dresden has some good potential.

Additional context
This will likely massively increase the search-space.
