You need to explain your problem better before we can suggest a simple solution. I still think the CC could be used to provide a second level CC but perhaps a userform and vba is going to be required.

I can't see how you can isolate 200 options from making a couple of choices from a list of 4 options. By my reckoning it will take a series of four choices each of 4 four choices to reach a number over 200 (4x4x4x4 = 256).
