Make it so Join only pushes the newest notification and not the group of all of them

What I mean is, when I receive a notification from whatsapp and do not answer/open it in my phone, even if I dismiss it, the next time I get  another one from whatsapp I receive two pushes with the first one and then the second one.

Is there away to avoid this happening and receive only the "unread" ones?

Hope I made myself clear, if not don't hesitate to ask!
