Gap between tracks

Yes. I found out that Helium puts the Grouping to CONTENTGROUPDESCRIPTION. I can now use this tag for grouping, but it’s not a good idea because I can’t change it easily with Audirvana. So I’s like to have a program which can take the tage CONTENTGROUPDESCRIPTION and put it to Grouping. Does something like this exist? May be a tool for the command line, so that I can change all the files in a directory? I can’t find any program which can do this.
