How to list all the configurations of an assembly in a Solidworks drawing parametrically?

Hi,

I have an assembly file with multiple configurations in it and all the configurations are created manually without using the design table.

Now I am creating one drawing to detail all the configurations.

My problem is, I have 7 configurations and each configuration assigned with one part number of 12 digit, in the BOM I am not able list the all the configuration number while indicating the quantity as configuration number is lengthy. So I want to call the all the configuration numbers and indicate a short name for it and then this short name I will use in BOM table to indicate the BOM quantity.

Bit Confusing but if you see the image attached you can understand.
