I currenly have a site that uses greybox to launch links.

I am using the load external links method (full screen and dimension). Is there a way to alter the scripts of greybox to do the following.

1. Load the page directly in the center of the screen. Currently the page loads center top.

2. Is there a way to set the opacity level of the page that loads. Meaning I would like to see a little bit of the mother pages behind the popup.
