Saving two address values in one CDT

Hi,

I have a address cdt . In the interface below i have two section temporary and permanant address.

So when i check box ( i,e : is temporary address same as permanent address) the address should be saved .

my requirement is : if the check box is not selected

both the temporary address and permanent address should be save and if its selected both the address saved. But it should be saved in the same cdt

So can anyone help me on how to solve this
