Yes. There are a few ways you could do this.
You could write some sort of ruby script to parse the text you just  
entered and generate the code.
Then bind that command to some sort of keystroke or tab completion.

Or you could write a really complex snippet using multiple instances  
of the same variable.
You can even have some of the instances of the variable use regex  
replacement to change the capitalization and let you insert an  
arbitrary number of objective-c instance variables with the  
corresponding code.

Check the help docs for the syntax. Check out the objective-c bundle  
for examples.
