Help with toolstrip overflow

I'm trying to use a ToolStrip but I want to use a table layout to do a 2
column strip. The table layout disables the overflow features you get with
the other layout engines. I have two problems. First is I can't get my
ToolStripSeparators to to be horizonal in this layout and I can figure out
how to make them span 2 columns. Though If I could get it to be horizontal
this may not be a problem.

Second is I can't find any examples online for faking the over flow. I've
tried by putting a dropdown at the end of the ToolStrip and when the Layout
Completes adding items where Placement != Main to the drop down but I can't
seem to get it to work. Thoughts?

Thanks
