So, I seem to have a pretty common problem: I have a "product family" that has 5 to 10 models per family. I created a product and added the models as variations.

Seems to work great for my purposes -- except every single model appears as "Family Name." Not, Model 1, Model 2, Model 3...

The entire internet seems to suggest that the fix to this is to just turn off "Auto-generate title" in the "manage fields" section of the product display/product variation screen.

I can't find this check box, at all. I have gone around in circles through the GUI looking at that darn title field and this mythical auto-generation title check box just continues to allude me.

Where is it actually found?

(Step-by-step instructions are required here, apparently. Using the default admin GUI theme boxed with the newest Commerce Kickstart package.)
