Send text to 2 people through 1 favorite?

[Gadjetguy]

I am trying to send one text to update Facebook and Twitter at the same time through one favorite entry under the people tab. I tried making a single contact with the Twitter number 40404 and the Facebook number 32665 but both numbers don't show when I click it under favortite people. I have to add the second number manually each time.

Any ideas?
