Add an option between RIFF ID3V2.4 and ID3V2.4 RIFF for WAV files

I have plenty of wav files with Chinese tags, and I found in RIFF ID3V2.4 style the Chinese tags were unreadable in MPD client while the ID3V2.4 RIFF style were OK. I wonder if you can add an option between RIFF ID3V2.4 and ID3V2.4 RIFF. The tags modfied by MP3tag are always in RIFF ID3V2.4 style. Currently I have to use KID3 to remove tag3 first and then copy tag2 to tag3, then I got ID3V2.4 RIFF style.
Thanks,
