When my girlfriend texts she never sends a complete text. She sends multiple text for one sentence. For example "Good morning"... "how are you"... "did you have any breakfast"..." I still haven't eaten". My phone vibrated 4 times in just a few seconds, and that's just her saying good morning.

She is not the only one, group text threads can get like this as well. So is it possible to give one notification of a person/group sends multiple texts in a matter of seconds.
