Non selectable Attributes to be displayed on individual variations

Hi

Is it possible on a variable product that has say 3 variations to have attributes that are common on 2 of the variation products but not on one of them but so they do NOT display on the product page as “selectable” with a dropdown menu.

I would like the attributes to display in the product table when a customer selects the variation of a “selectable attribute”

e.g. to make it simple

I have a book that has 3 choices (selectable by dropdown menu) of colour red, blue, green.

The green book and the red book both have 300 pages but the blue book has 500 pages.

Wanting to display the number of pages attribute in the product table but don’t want the customer to be able to select which book he buys by number of pages. Just want the attribute to be standalone and changes depending on what colour book the buyer selects.

I hope that makes sense !
