hidden Posts in Main page (more complicated)

Hello guys!

As the subject states, i’d like to have some posts hidden (not showing) on main page and showing on all other pages.

So i now know how to achieve this, if putting these hidden posts into separate category.

But! This doesn’t suit me well, i need to have a single category both for ordinary posts and for hidden posts, let me explain.

Let’s say i have a category ‘Movies’. I have some posts in this category viewable both from Main page and from category page. But at the same i’d like to have some other posts to be viewable from the same category page, BUT not from the main page.

Would appreciate any advise on how to keep the posts hidden without messing with different categories! Thanks!
