Hi,
Ok, I see.
You can override some views in order to change how the system works but you have to find the right event when the address will be "reset".
If the customer click on "checkout", HikaShop will ask him a new address but, if he go back in the store to add another problem and return in the checkout.. Will HikaShop ask him a new address again ?
I want to say that you can do a lot of thing using view overrides but for such feature it needs some specification before doing any kind of modification.
