For example, I want to specify http://www.gearogs.com/gear/2647-KRK-Rokit-5 to be the 3rd generation of the Rokit 5 due to some slight differences between generations.
I put Generation 3 at the top of the notes, but it might be nice to have a dedicated field... what do you guys think?
How are the different generations distinguished? Is there a different model ID?
I'd think this should go in either as part of the model name:
Rokit 5 (Version 3)
Or in the "Additional Model ID" field (if the model ID is different).
