Feature Request: Inheritance of values for categories

When I am creating default values for categories on my site, it would be great if the system looked at values from parent categories. At the moment it only takes values from the lowest category in the tree.

Fore example, I sell fabric of various types and sizes, my category tree looks something like:


Fabric
Fabric > Aida
Fabric > Aida > 14 Count


For an eBay feed for example, I wand to define the "Category" field at the "Fabric" level, the "Fabric Type" field at the "Fabric > Aida" level and the "Fabric Count" field at the "Fabric > Aida > 14 Count" level.

At the moment I have to define all of this at the "Fabric > Aida > 14 Count" level and repeat it for all categories in the Fabric section.

Please check this logic again.
Plugin has such logic.

Category1-> Category2 -> Category3 - Product

Plugin tries to read information for the first level (Product)  if Product doesn't have any information plugin tries to read it from Category3  if Category3 doesn't have any information.....

But you will not be able to save different information in all levels and read it at once.
Example.

          Category1-> Category2 -> Category3 - Product
Color     red                 -                    -             -
Style      -                    -                   modern    -
Size       -                    -                    -             XXL


Plugin will read only last level
Color     -
Style     -
Size      XXL

But you want to have
Color     red                
Style     modern    
Size      XXL

Am I right?

Yes, that is right

I must think how to do it...
