Variant BOM Populations

I'm wondering if anyone has any thoughts on the best way to communicate Variant BOMs to contract manufactures.  Take for instance an arbitrary Resistor, R100, which is 10K Ohms in the base design.  We may have one variant that uses a 10K resistor there and another design that uses a 2.2K Resistor in the same R100 location.  Currently, we use the variant editor to set this up, and when we post-process the BOM to put it into a clean format, what we do is show something like the below:

I know that this is confusing, but I'm not sure of how to make it not confusing.

Thanks for any input.
