Agregator and Scheduler hard question

Hi,

I have o block defined. Content of this block is updated by agregator from one category. If there is something new in that category, it is by agregator pushed up to the block on the title page (every 15 minutes).

But I am using scheduler to hide some content after defined time. So, Scheduler make concrete article unpublished (hide), but agregator dont remove this article from block :( Do you have any idea to slove this problem?

thx
