Well, since no one bothered to answer my query, I pressed on and found a workable solution.
It turns out that each browser contains a place for an address book within the Privacy and Security section in Options. I looked at Chrome and Firefox browsers.
If you go to that section and enter in the addresses that you most frequently ship to, then when you are using the PayPal shipping module all you need to do is click on the "Customerʻs full name" box and the list of addresses which you entered into the browser will appear. Choose the one you want and off you go. I should note at this point that this option works well with Chrome but is only half filled in when using Firefox.
