How can I change the listed artist for an album entry from Various Artists to something different. When I select the right arrow next to the Artist field, I only get an option to file under Various Artists.

For example, I have an album for Artist_A and one or two tracks might feature Artist_B or Artist_C. OrangeCD seems to be filing all of these under Various Artists, when I would like to file them under Artist_A.

Is there a way to solve this? Am I missing something obvious?
