make blogfeed category content writable if used in an article template for articles which use this template

Please, make the blogfeed displayed category content writable if used in an article template for articles which use this template. Why? An example:

I have an article template for the article "Music Genres". In my article "Popmusic" I use the category "Music Genres" an the "Music Genres" template. I want to present all my "Popmusic Singles/Albums/.." in my category "Popmusic". But if I try to edit the article "Popmusic" I can edit the image, the header, the name and links of buttons, html content, but not the content of the blogfeed which shows my articles. It should only show articles of the category "Popmusic" and not all (as it is fix defined in the template). Thanks a lot.
