M4A files don't read nor show Camelot KEY info. in the Key column.

I have a few 100s M4A files from my beginnings : Rkbox DJ software doesn't read nor show or write their Camelot KEY info. in its Key dedicated column, unlike it does for my Mp3 and AIFF files.

I'd like it to work as it would spare me (and most likely 1000s of other DJs) 100 hours of work entering the data manually one song at a time, many thanks in advance. Please look at my next post about fully integrating Mixed in Key or at least the Camelot system.
