@l-andorrĂ I know you can do so either. If you have some spare time, here is all you need (from what I see at the moment).
Use this version! I only added lables to the 2 buffers.

Use those settings!

Buffer considerqations:
For usage, please bare in mind that the 2 buffers only show the next news event that is a valid entry due to configuration. So for instance if you want low and medium news covered and 2 events of each time occur at same time and for some reason the medium news is found first, it will display the 2 buffers only for that one. Hence, if you plan for more than one news type, I'd suggest to make 1 configuration per news type!
Does that make sense?
You may start a project and share the results to us.
