How to show different alternative messages (banners)?

Hi, just want to ask you if it’s possible to make not just 1, but 2-3 different alternative messages (banners) that will be shown on different places on my website (separately). I tried to put 2 banners, but it always shows me these banners at the same place, but I need only 1 at this specific place. So, is it possible to separate them?

Thanks in advance!
