Independent page panels

I have a solution which works in Evo but I can't get it to work in Revo. I'm not a coder through and through, but I can handle some coding. Anyway, the scenario is this:

I want to be able to have a bank of panels, which can be applied to any page, and more than one panel can be assigned to a page too. The panels are resources, grouped under a parent resource, called "Panels".

When adding a new page/resource, a list of the panels are shown as checkboxes, and the user can select any number of those panels to display on that page/resource.

Anyone have any knowledge of how to do this? I would imagine this is quite a common thing to be able to do, a bit like having a bank of "banners" which can be assigned to any page etc.

Thanks in advance.

Is there an extension that may help?

It sounds like you want a checkbox Template Variable. Have you tried that?
