HI, iam using PayPal IPN (Basic PayPal service) Is Multiple Stores With 1 Paypal Account Possible???

Went to set up new store but these Configuration are already in my Paypal.

set your Instant Payment Notification Preferences URL to:
http://default web site
(If another URL is already used, you may leave it alone.
in Website Payments Preferences set your Automatic Return URL to:
http://default web site/index.php?main_page=checkout_process

So how would i add a new store to this account, is this possible???
