Hello Paul,
thank you, it's an interesting solution and I like it. I will definitely try to learn it for myself, but another problem of mine is the fact that I will have to share this work with other people, who would surely not find it so intuitive to use. I would stick to a more "classical" design to facilitate the acceptance of this work.

Out of curiosity, may I ask you if there's a way to open a PDF file with the results of filtered slicers?
