As I stated above, I have a 3dsMax script that does this, so if your artist uses max I can send it to you. It has a gui and is dead simple to use.
Before this script, I used to split out the alpha and color into individual files, sequence them with a small blitz program I wrote, and then take the 2 outputs back into Photoshop where I would combine the alpha with the color again. Don't know if that is any help, but it worked great for me until the (3ds)max script.
