Magento "enhanced order filter" modification

Magento store website uses adjustwares "enhanced order filter" to show ordered products in the backend order list page. ([login to view URL]) Since my site uses "configurable products" extensively, the listing shows two (redundant) entries: the "base product" plus the "configured-product" (the underlying simple product). The task of this project is to display only the "configured-product", which shows all necessary information. see attached photo for detail.
