Domino Designer / : Make Subforms Objects

I want to be able to include the same subform on a form multiple times.

 

For exampe if I were making a billing system it would require several addresses; order address, billing address, shipping address. Then I could build one subform; address. Then I could include it three times, each with a name. Then I could reference the fields on the subform using name-spaces such as order_address.city, shipping_address.zip, etc.
