Album Artist Field

Would it be possible to have an option "same" added to the Album Artist field. When editing multiple albums it would be great to be able to select all and choose "same" and have the album artist on all be set to the same as the artist field.

There are other simple ways of accomplishing that in Mp3tag. You can use a 'Quick' Format Value action to copy ARTIST to ALBUMARTIST. Or the Tag-Tag converter.
