Add Widget area for special page!

Hi there.

I have a Plugin for which i need to add widget-functions!
The Menulink of this Plugin is solved as a “page”.

My problem is, that i cannot just add the widget-functions to the normal widget-page menu because on other pages i need different widget-infos! AND on the other hand the widget-functions of this plugin wouldn’t make sence on other pages.

So i thought of a theoretical solution: Another Widget-Area (is this term correct?). How do i add another widget-area just for my plugin-page?
