How about a defeult option in the ingredients add-on?
For example: Red meat served ‘rare’ or ‘medium-rare’ may be undercooked, so many restaurants will serve to-go items at ‘medium’ unless otherwise requested. Taking a phone order gives you the ability to ask, but if your custom group involves meat temperatures, (rare, med-rare, med, med-well, and well) perhaps a way to have and option (Medium) chosen by default. This way, in the event that food IS undercooked, we can show that it was requested that way.
