Hi,  
I couldn’t find the possibility within the API but do you see the possibility to obtain a [Shortest-Path Tree](https://www.graphhopper.com/blog/2016/01/19/alternative-roads-to-rome/) with Openrouteservice?

edit: Getting a quick overview in the codebase wasn’t possible for me, but if you say it could be implemented easily, I would be happy to dig deeper and try to open a PR…
