Hight précision Currents files GRIB

[TUF TUF]

Good evening, I sail a lot in regattas in the English Channel/Ireland/East Atlantic. Current plays a major role in routes choices.

The internet https://baroropic.frsite provides with very high precision grib files for currents.

Unfortunately, it is not possible to play these files with OPEN CPN. Is there any way to use theses files in the routing modules of OPEN CPN?

Thanks a lot for your return
