"Ensure Sort Artist and Album Artist are identical" feature is not useful

```
Due to the way iTunes (now) behaves, the above feature, on its own, is not 
sensible. When sorting a library by album artist, the "Sort Album Artist" tag 
is used, not the "Sort Artist". Could you provide a feature to ensure Sort 
Album Artist and Album artist tags are identical?
