XF 1.4 Adding custom sidebar to right of a category node below notice bar

I was wondering if it is possible to place a custom side bar specific to a category node but is placed below the notice bar. The example below is a category node with forum nodes listed.

I can add a sidebar to a specific node BUT it puts the sidebar to the right of the notice bar causing it to shrink. Also, I can't seem to get a sidebar to display within a CATEGORY node, only a FORUM node.
