FOLDERCONTENT Customisation Question

Go PATH="C:\" NEWTAB=findexisting OPENINLEFT FOLDERCONTENT=nofiles,showempty

Is there a way of forcing NEWTAB and OPENINLEFT/RIGHT arguments to be passed to the menu items that are displayed by FOLDERCONTENT? The sample code above does not do what I'd hoped, perhaps not surprisingly. Clicking an item replaces the current tab in the source lister.
