Dial Contact - Choose Cell/Home/Office?
 

When I have more than one phone number set for a contact in my iPhone, my vehicle asks me to choose which one to dial based on a number i.e.: #1, #2 on the list of available phone numbers.

Is there any way to have the system know the difference between the contact's cell phone and office? I notice that the system is smart enough to display the right icon beside each of the person's phone numbers ie: office number has a building beside it, etc.

I'd love to be able to say, "Dial Amanda Gil's Cell Phone" or something to that effect.

Thanks
