How to trigger a second label to print when another one is printed through Commander 追蹤

I have two 12" labels that need to also print a 2" label each time the 12" is triggered by Commander.

I tried to add a second template, but that doesn't allow a different size of label to be chosen... Unless I'm misunderstanding that...? 

If that is correct, [and I can't add a different sized label with a second template], how to I trigger the 2" label to print when Commander gets the request for the 12" label?

Do I have to create a stored proc in the DB that also sends the data (and create another *.dd file) for the label or is there another way that I can trigger the 2" to print each time?
