Reader DC Customization Wizards - SharePoint Site

Hi

I'm modifying the installer using the Customization Wizards and would like to add a SharePoint site account.

I know i can add the site manually after installing the reader by going.. Home > Ad Account > Add Microsoft SharePoint. but I have 80 users and would like to integrate it.

Is there a way to add SharePoint site account to the Customization Wizards, i could not find it.

Thanks
