AFAIK no, but I know of two possible work arounds... first is to write multiple copies of the function to accept the different number of argument combinations you need. the other thing i've done in the past is to create the function as accepting a array as one of its inputs and then handle the array structure as needed. (bonus points for doing the second method in 7.3 where its much more challenging.)
