Menus question

Hi all,

Just a quick one. I am setting up an online store using wp e-commerce plugin. It maintains its own set of Categories called “Product Categories”.

When creating a Menu in the WP dashboard (Appearance->Menus) there is a widget there to assist putting in the WP categories. Is there anyway to add another widget to that can help me add in the Product Categories. Currently I can add them in manually by creating Custom Links, but this is quite a tedious task for so many categories.

If there was a way to add in the Product Categories such as you can do with normal Categories, that would be great.

Any ideas?

Thanks heaps!
