[Q] "Hide sensitive content" for selected apps topic

I noticed that on CM12 the lockscreen notifications can be hidden one by one, but on Touchwiz Lollipop I can only hide ALL notifications. I just want to hide Whatsapp on the lockscreen but see al the other notifications. I don't want to see "Content hidden" even on the Screenshot Captured notification or the Battery Full notification (not sensitive notifications). Anyone knows how to manually hide app notifications? Maybe with an app or a code, idk.

Sorry for bad english, hope i'll be understood.
