Using 'Magic Fields' and 'Map categories to pages'

I used ‘Magic Fields’ to create a custom write panel called ‘test’ and I created a custom page template to create a test page using the write panel ‘test’..

I have a category ‘test’ in a local test site that I am experimenting with which has a few posts.

I want to map pages to categories, so I also installed ‘Map Categories to Pages’ plug in. Now there is an option to set a category for any new page that I create.

But there is no option to set a category for pages that I create using the custom write panel. (Once I created the write panel, it automatically added a menu item ‘Test’ with a sub menu item ‘New’.. If I click on it, it will list all the custom fields that I created. I already have a page template created for this write panel, but I also want the pages created using this write panel to be aded to the category ‘test’. )

The idea is, I want a page in my blog (similar to the archive pages for category, tags etc) that lists all the posts which are in ‘test’ category and all the pages that I create using the custom write panel ‘test’.
