Tracking with Parcelsapp?

Hello, 17track doesn't seem to work well with my parcel tracking. No infos are displayed whereas on Parcelsapp everything is nice and neat with all the infos included. But tough luck no "parcelsapp" integration in the "tracking services options" of ADS. Would you know how can I manually redirect trackings to the parcelsapp website ( By that I mean modifying ADS files directly on my FTP.
