individual names to multiple instances of same assembly

Hi,

Is there a way to give individual names to multiple instances of an assembly within a top level assembly that is displayed in the feature tree? I have a relay box as the top level assembly. Within it are 13 instances of the same relay socket assembly, however each instance (part number 000300-1490) has a unique name (K1, K5, K13, etc.). I would like the feature tree to show the unique name but have the BOM display total quantity of the part number.

Thanks in advance
