When creating a new project and working through the wizard, when you get to the addresses part of the wizard, if the site address you need isn't already part of the customer, then you need to either stop, close the wizard then navigate to the customer and add that new site address OR you have to leave it blank and finish the wizard then add the site to the customer addresses the return to your project and add it OR you can add it manually in the wizard, but it doesn't add it to the catalog and doesn't help others in the future.
We need the ability to manage customer addresses when working in the Wizard. Sometimes you don't know if the address is already attached to the customer or not until you get to this step in the wizard, then it's frustrating that you cannot just add it to the customer right there.
