What you need is a "plain text route entry" box like Flitestar has, into which one can paste a route generated by e.g.
FlightPlanPro e.g.
EGHH SAM L620 MID M140 DVR L10 RINTI B3 CMB/N0150F140 B3 RLP G4 HOC L613 RIPUS N850 ODINA M727 SRN L153 PAR L995 FRZ M730 ANC L612 BRD L995 TIGRA LGKR
and it plots this route onto the map, and then you can 'walk' along it to pick off the tafs and metars, etc.
