music product with sheet music

I have a client that wants customers to be able to purchase CD's and Sheet music seperately, but when a CD is purchased the customer get a free copy of 1 set of sheet music. Not just any sheet music but shee music of the same name.

Example
Amazing Grace CD
Amazing Grace Sheet - Alto Sax
Amazing Grace Sheet - Clarinet
Amazing Grace Sheet - Flute
Amazing Grace Sheet - Trombone

each of the sheet music instruments are products that can be bought seperate of the CD but one will be provided free when the CD is purchased. How do I get this set up with the option name/value attritubes?

Been playing aroudn with ZC. Looks like I have to have 2 seperate attributes on the CD products, the first attribute is a single attribute for the music file and a second attribute that only allows for 1 of the many sheet music that can be combined with the CD product.

It doesn't look like I can do a combo deal of 2 products that are already in the system. Did I just miss it, or is there not a wahy to do combo pricing yet?

Products cannot be used as attributes of another product at this time.
