Extend ListViewByQuery functionality

I have a SharePoint list with custom display form. On that form I have a ListViewByQuery control which queries an other list and displays its related elements.

However I have a new requirement. I need to put a button before each related list item (in the ListViewByQuery control) to be able to do some work with the item when I push it.

I thought it would be great idea to extend the ListViewByQuery class but it's sealed.

Has anybody any idea what other control could I use for this purpose from the Microsoft.SharePoint.WebControls namespace? Or may be from another?

Thanks!
