If I'm searching a round trip with multiple airports in the destination field, how do I force matrix to return round trips from the same airport?
Ex: if I'm searching for "NYC" to "CHO, CHS", sometimes I get mixed airport flights, like EWR-CHO CHS-EWR. How do I force Matrix to only show me NYC-CHO-NYC and NYC-CHS-NYC separately without needing two separate searches? If I uncheck "allow airport changes" it doesn't show connecting flights.
Edit: I _think_ I got it to work like this (using UA+ instead of UA in the routing code):
