Only with 3rd party apps that support customizing notifications, like Lightflow. Bear in mind, however, that some have compatibility issues especially with Samsung devices, so try them out before buying. A vary famous 'bug' with LightFlow and Samsung phones was that it activated (and kept active at all times) the TalkBack service so everything you did on your phone was narrated out loud to you. It's most likely fixed for your model, but I can't be certain. Users of the S7 are reporting other types of incompatibilities. Of course, LightFlow is not the only notification app out there, so feel free to try them out!
