[Plugin: WordPress Portfolio Plugin (WP Portfolio)] Want to capture internal site pages

Hi, just signed up to be able to display internal site pages.

Shrinktheweb docs say you need to:

Specific Page Capture
• &stwinside=1 *Add this tag to all requests except when homepage desired

How would i go about this or is this a feature that you would need to add?
