Besides opening the Wavelab 7 montage in Wavelab 8 or 9 and exporting there, no I don’t think so. You’ve only got ID3v1 in Wavelab 7, so doing it in Wavelab 7 you’re not going to get the ISRC field. Or the CD Text Title or Performer. Just the file name as metadata Title I think. You need ID3v2 and ISRC and CD Text mapping in Wavelab 8 or 9 to do what you want.
