Customizable Post Listings

I am using the Customizable Post Listings http://www.coffee2code.com/archives/2004/08/27/plugin-customizable-post-listings/

And would like to know if I can exclude the entries already displaying in the home page while I am showing the last 15 recent entries in the sidebar. I mean I don’t want the plug-in to show in the side bar the entries already being displayed in th front page.
