Is your feature request related to a problem? Please describe.
I have a very long station platform, with regularly spaced train arrival boards. I can't reach all of them with a display link.

Describe the solution you'd like
A block that acts as both signal target and signal source, allowing signals to be split among multiple displays, or for the reach of a display link to be extended.

If you need to, display link range can be changed in the config under Gameplay Settings -> Logistics.

Alternatively place a track and a station, then remove the track so only the station remains. Place the Display Link on the station then change the station name filter to the station you would like display. Not the most efficient solution but works.
