EPDM thinks changing a config of a part inside of assembly = changing the part

We have standard purchased parts with multiple configs in our Library.   When I drag/drop one of these parts into my assembly, then change the configuration, EPDM sees this as the part was changed, prompting the "do you want to checkout" window.  I know you can uncheck the setting to prevent this notification from popping up but I want this notification for parts are truly changing.  Why does EPDM think a configuration change is considered a change inside of a part?   Any workarounds for this?
