How can I select "two" models?

Hello there, dear Visual Scripting community,

I am once again here to ask for your help. I am currently working on a wardrobe with multiple configurations of materials, lenght, components...I managed, with your help, to program how to make certain components disappear by chosing a material, but now I am stuck with another variable. 

 

Basically, this panel has 3 different posts (X, Y and C), with a total of 5 combinations:

  • XX
  • XY
  • YY
  • XC
  • YC
  • (there is no CC, for now, but I used it sometimes for balance)

 

So, three posts, coupled together, for five possible combos. I tried making a list of the combos and a list of the components, but I can't seem to be able to tell the model to show only TWO posts. Also...since the combos are five, but the posts are three, I have difficuties using the indexes...

I can make two lists, like here, but this makes it so that our customer has to manually select the posts twice. Is there a way to select the combinatons? FE By selecting the XX configuration, only the X post shows up, twice. Is it possible?  

I tried with multiple sketches as well, but I wanted to know if there is a way to make a list that generates outputs that trigger ONLY some components. 

Any help would be appreciated. Thanks!
