The same part with two different configs in an assembly?

I have two identical COTS parts in the same assembly. I now need to modify those parts but, they each need different features. Obviously any changes I make using the "Edit Part" command get added to both instances.

I would prefer not to create another instance of that part. I assume there is a way to suppress features on one instance only.

How do I configure the same part in different ways within an assembly?

Thanks in advance for your time.
