Ringtones on the Motorola Electrify

Having just bought a new Electrify through US Cellular, I am finding it very difficult to try and organise individual ringtones for incoming text messages. I have just changed from a Blackberry Torch to the Motorola. My question is, is it possible to set up individual tones for text messages? Yes, I know that I can set up a tone for text messages, but can I set up a specific tone for texts from person A and another for texts from person B?
