When you have a conversation open in WhatsApp, if you select Menu -> More you'll see a dialog that includes "Block". I haven't used it, so I don't know that it does the same thing you're looking for, but it's worth a shot.
Or, you could contact the WhatsApp folks (Menu -> Help -> Contact Us) or android-support@whatsapp.com and see if they can include support for system-level notification blocking.
I have found a way to do it.
You will need the LightFlow app, which i believe is a must have app for the S3 anyways.

after you got light flow:
1: In What's app:
- disable notification sounds for incoming messages(not in light flow, in whats app). set it to silent or disable at all
2: The go to light flow and:
- enable sound notifications for whats app
- set what ever notification sound you would like to have for whats app when blocking mode is NOT enabled
- under Sounds-->Volume control method-->tick "Android standard notification volume"
Now it you enable blocking mode, it also blocks what's app sounds and if blocking mode is disabled, everything is normal.
hope that helps....took me quite a while to figure it out.
edit: oh and i do not have any affiliation with the light flow app or their developers!!! i just used it for changing lights and came across the sound feature by chance!!!
