Enable/Disable Routing only with circuit signal

[foivos]

Currently there is capability to Enable/Disable train stops with circuit signals. It would be great if you could disable only routing to those stations, with trains inbound keeping the stop as their destination.
With complex enough circuitry you can force trains to route to a specific station among stations with the same name by disabling all but one of them. Say you successfully routed 2 trains to the first of five stations named "Iron Pickup". In order to route a third train to the second "Iron Pickup" station you currently would need to disable the first station, and the two outbound trains would reroute. With the suggested functionality this would not be an issue.
The implementation could be as simple as a check box on the "Enable/Disable" sub menu of circuit logic of train stations titled something like "Let inbound trains arrive"
I am aware of the existence of the mod LTN, which is great, but being able to create complex systems out of simple parts is part of the fun in factorio and LTN somewhat takes away from this.

The suggestions linked suggest a different way to address the same problem. The mod posted also is a different workaround, so thank you.
