I'm away from SOLIDWORKS at the moment so on't be able to check the files. But please move this post to design table category (use move option on right side under actions)
Let me explain
Part 1 has config 1, 2 and 3. And Part 2 has config X, Y and Z. No in the design table you can create list of configuration names for both. And then using lookup option you can set the cell values for the part 2 configuration base don part 1 configuration..
