Attach all files from single multi-value cck filefield

Love this module and it does exactly what I want to do, except for one thing. Forgive me if I'm dense and missed something, but I cannot get multiple files to attach to my outgoing email triggered by rules.

I have a single CCK filefield that allows unlimited values. I only ever get the first value as an attachment when I send an email from a node with multiple values in that filefield.

Is there a way to make this work, or do I need to totally restructure how my nodes accept filefield attachments (ie multiple single-value cck fields instead of one multi-value one)?
