product part number from atributes

i'm needing multiple part numbers for an item based on what items the gust selects.

for example:

i'm selling widgets in 3 colors (Red, Green, and Blue) and 3 sizes (Small, Medium, and Large)

a Small Red Widget has the part number WDGT-S-R
a medium Red Widget has the part number WDGT-M-R
.
.
.
a Large Gree Widget has the part number WDGT-L-G

and so on and so forth.

the manufacture only wants the part number and quantity in an email not size color type.

is there any way to do this in zen car ether with a mod or trickery or do i need some other car program to do this?

Thanks
Steve

You can start with the module here Stock-by-attributes and then determine what needs to be included and or omitted in the order confirmation email.
