Equation driven Configurations.

I am setting up a template file with equations and an equations txt that is filled in to drive selections of parts, sizing and was wondering if it is possible to drive the selection of a configuration in a top-level assembly via an equation. for my case i have 5 configurations (at the moment) that i was hoping to drive via equation if statement (if "random property"=1, basin, if "random property"=2, Bin, etc...) or some other way. i have if statements driving whether items are turned on and off based on what is required but would like to avoid having a separate model for every one, if possible, as by then end I will have mountains of suppressed parts that wont be needed.
