Create part configurations from design table in assemblies.

I've been trying to automate the assembly process for my company.  Most assemblies are exactly the same but require different configurations of parts.  So, here is my question:

Is it possible to create different configurations of a part from a design table in an assembly?

basically I want to enter in the width and the height of an assembly and have the parts create a configuration of the needed component.

thanks for all of your help!!
