Galaxy S3 - Message preview question

[xhydeffx]

So I just updated my s3 to 4.3 and I love the new message preview function on the lock screen, but I'd like to customize it a bit more. Now I know you can turn the preview on or off so it shows the whole message and sender or just says you have a new message. But is there any way to make it so it shows me who the message is from, but not the message text?
