Filter by inbound vs outbound

Feature request sent to our email:

Can you add a filter to allow you to only look at inbound vs. Outbound. Thanks for considering.

It will be great if there is a selection for looking at the trains inbound versus outbound.

Not sure if it would be better to filter by northbound vs southbound, not sure if the API gives us those values and that would avoid downtown just being empty when the filter is active
