Is it possible to insert a comment within the Album Field

How can I batch insert a comment in the Album field for multiple Artists.

i have about 120 - Singles/Maxi CD's - which i would like to distinguish from the actual complete album by inserting a caption.

Example:

Album: Bad
Album: 1999
Album: Wall
Album: Madonna

Change to

Album: Bad - Maxi CD
Album: 1999 - Maxi CD
Album: Wall - Maxi CD
Album: Madonna - Maxi CD

Thanks

Action: Format Value
or
Converter: Tag-Tag

Field: ALBUM
Formatstring: %album% - Maxi CD

Cool, thanks
