How to select several roads at the same time on Yandex maps?

Question

JavaScript

The point is this. There is a rendered map on which about three dozen toll roads are highlighted at the same time. The task is to implement this in Yandex maps. I poked around the API, but apart from building the route, I didn’t find anything - I just need to highlight several pieces of the highway with color. I would be glad if you tell me where to dig!
