[support] approach with multiple levels of data

Hi folks, here is a question about approach. I have a site design which has several large content modules, and within them, several sub-modules. If I had only one module per page, I would do the following: 1 panel 1+ views which call up the respective nodes But now I need a page that has: several panel-blocks with x views per panel they need to be grouped like this, because each content-module has a collapse/expand button, which will hide all the views associated to the that panel [with a jquery nice effect]. ... I don't think this can be done with the way panels work..., unless there is a way to add panels within other panels? or another way to implement? any suggestions? Thanks! Sebastian.
