Is your feature request related to a problem? Please describe.
No.

Describe the solution you'd like
I want a method to read the same data with a display link that the advanced display can display, mainly the actual time of arrival for each train in minecraft time, delays and other problems for a train and all stations the train goes to.
The solution could be that display links on stations have an extra option, that there is an extra block that can be read or that display links can take advanced displays as a source.

Describe alternatives you've considered
The only alternative is the given way of using a display link on a train station which doesnt read the specific data mentioned above.
