FAI IGC file format support for paragliding

I use my watch to record my flight tracks when I go paragliding. In paragliding mainly the IGC file format is used. Is it possible to add this format as an export format? Or add a feature in CIQ to directly write this file to disk when recording?
The issue I face is that the IGC file has a checksum based on the altitude measured by the Barometer. If I just download the fit file and convert this to IGC, the checksum of course does not match the guidelines and therefore the file is not being accepted by the XC server where we usually upload our tracks.

Any chances of such a support coming soon?

Best regards
