How to add 24bit just to Flac files?

Can someone show me a string to write just so I can add 24bit vinyl to my Dir tags.
I only want 24bit for FLAC files I don't need it to show 16bit

example:
Artist\Album\FLAC [24bit Vinyl]

The easiest way would be to filter for flacs that have 24bit and then rename the folder.
Leaving out data has the disadvantage that one never knows whether the data has been left out deliberately or because the items have not yet been treated ...

Thanks for the reply I will look into this.
