Deductions & credits

I am still having problems with this. The construction loan is for the SAME house as the permanent mortgage loan it was converted into after the home was built. If I enter the two 1098's separately, I can only check box 7 for one of these to claim it as my address for a deduction. But since both interests amounts were used towards the same house (one during building, one after it was finished), should I be able to deduct both of these? Should I add the two amounts in Box 1 for each form instead?
