I'll have to take a look at this template and see what I can do. I did take a quick look and I'm not sure exactly what to do with it.
It looks like this is more for the front end, what the customer sees.
I'm not sure how to do this on the admin side of it. I know how to add options but in looking at the /modules/product_options/customer_options.tpl, how would it know how to display the correct option in the correct way?
I'll have to play around with this one. I'm pretty good at customizing the templates. Just not as sure about customizing things like this.
Thanks for the reply FunkyDunk.
