Fetured products on specific categories

I'd like to promote some products but adding them as "featured products", but i want them to be displayed only in specific categories.

e.g. Category 1 -> Subcategory2 -> Products 41, 42, 43
Category 2 -> Products 54, 55

Is there any way ?

Thanks !

I did an extension for that: http://www.opencart.com/index.php?route ... on_id=7472

Thanks mate
