integration SEBLOD: copy the address on an event

-- HikaShop version -- : HikaShop Business 2.2.0
-- Joomla version -- : 2.5.14
-- PHP version -- : 5.4.3

Hi,

I use the CCK SEBLOD, and with him I've extended the Joomla user, so that he has an address.
I want to make life easier for my customer so I want to copy the adress that is registered in Joomla, and put it in the billing address.
I don't want to do it at user registration because all my users aren't ecommerce customers, and I don't want to fill my database uselessly.
Si I was looking for: where to do that? The ideal would be to do it at checkout, when we display the adress, but I don't see on which event exactly I can do my plugin?

In advance thanks for your help!

Thanks for your answer, I tried it, but it works only if the user connects himself before the checkout.
But the user can add a product in the cart without being registred ...so if the user arrives in the checkout without been reegistered, and connect(or register ) himself at the beginning of the checkout, the popup appears to propose him to fill his adress and there's no automatic copy.

Isn't there a way to catch these events? connexion checkout/registration checkout?

in advance thanks for your answer.
