3-pane explorer: docking existing split container in new split container

I would like to create a 3-pane explorer-type form. The upper part of the form will be the standard split container with a TreeView on the left and ListView on the right. The lower part of the form will contain additional information about the item selected in the upper part. The best way to do this seems to be to have a split container with a horizontal divider, and dock another split container (with the default vertical divider) in the upper half.

I know I can create this from scratch in by designer mode, but the Explorer Form template gives me almost all I need, and I would like to start from that. The only thing I need to change is to add a split container with a horizontal divider and then dock the Explorer Form's existing split container in the upper part of my new container.

I can change the dock property of the split container to "None", and then drag the lower edge of the form down to make room below the split container. I can drag a new split container into the space I made, and change the divider to horizontal. But how do I take the original split container and dock it in the upper part of my new split container? I expected to see something like a "Parent " property that could be set to show which container a control is docked in, but I can't find one. Am I going about this in the wrong way?
