Topic As Announcement

First to note, this is not about the scrolling announcement but rather to arranging the topics. So in current situation, we have four types of topic:
1. Normal
It will go up if it has new reply.
2. Sticky
It will go up if it has new reply, but it will never sink under normal topics.
3. Announcement
It will go up if it has new reply, but it will never sink under stickied and normal topics.
4. Global Announcement
It will go up if it has new reply, always on the top, also appears on ALL sub-forums (category).

But is it possible to make an announcement to be global ONLY on particular category? Assuming the category has three different sub-forums, I am referring to make it appear on those three sub-forums. And, no, posting same topic on several topics isn't a solution since mentioned thread is supposed to be edited regularly. Posting different topic means you have to edit three of them.

Thank you.

Sorry it is not possible. Global announcements will appear in all forums and categories.
