Can't Set Custom Vibration Patterns?

Settings > Sounds > Sounds and Vibration Patterns. Under each alert type (Ringtone, Text Tone) at the top, there is Vibration. Select the vibration type there.

 

Two different vibrations?

I'm not having a problem finding the vibrations, but having a problem with the fact that Apple overlooked part of the custom vibrations (unless I'm missing something?). I prefer to have a very light vibrations for certain contacts when they message me. Using the custom vibrations I set it up so that this works perfectly from the lock screen, or when I'm not actively using that message thread for the contact. The problem is that when the message thread is open and the contact replies, the DEFAULT vibration is used (two short strong vibrations). Is there any way around this? This is using iOS 6 on an iPhone 4.
Thanks!

 

That happens to me with various text tones and having the default sound in an open thread. Maybe Apple did overlook this; I wonder if their reasoning is that you don't need a special vibration whilst in the messages app because the screen is showing you who it is you are chatting with.

 

That's a good point, except I guess maybe I'm too neurotic and want minimalist vibrations, but compared to the blip of a vibration I have it set to, the default is like an earthquake. Maybe they will address this some day.... until then I had to turn it off!
