Cascade tagging options - Metatagger taxonomy

System

Hi,
I have a browse only taxonomy built & published to TS (6.7.1) using metatagger (4.1.1). On my DCT, I am using the tagging option to tag the content I am creating to this taxonomy nodes.
When I get to the tagging screens, I can search for the taxonomy node & then can add the node or refine the node and choose a child node of the taxonomy - so far so good.. Now if I wanted to do a cascade at the parent node level is it possible using out of the box configs? If not, is there any elegant way to go about it?

Thanks
