Xperia Z5 :: Mute WhatsApp Notifications

Before buying Z5 premium dual, I had been using Z. In Z, I was able to have Whatsapp messages appear in the notification bar WITHOUT any sound. That allows me to see the messages without triggering the blue ticks.
 
Now in Z5p, I am not able to do the same. From the settings available, I only have two choices:

1. Whenever there's a whatsapp message, it pops up at the top of the screen WITH sound, then it remain in the notification bar.

2. By choosing to block it, nothing will ever pop up, there is no sound, and there will be nothing at all in the notification bar.
 
What I want is "showing up in the notification bar" + "NO sound", is it possible to do this?
 
I have read some forum posts in which people suggested to turn to silent mode. But in this case I won't be able to hear phone calls so it's not feasible.
