Enterprise One Option Dependency Selection

We at Shea have a question that I think someone within the SIG group may be able to help us with.  We’re struggling in our purchasing group to set up options that have dependencies.  For example, an option  is selected that converts a garage to an additional bedroom.  The bedroom option then has options that are required to be selected or dependent, due to the configuration changes, that may add an additional door, closet door, door hardware, etc.  Then an option is selected, and by selection said option, there are several dependeny options (with multiple choices) are required, this is a real pain point for us and I’m sure other homebuilders have faced the same dilemma.  I am hoping that someone within the SIG group would time for a quick call sometime, do discuss how you handle this issue.  Any help anyone could provide would be greatly appreciated.
