Look at the code for the table you want to display these on - what component="" is the table currently set for, and what is the <list> expression? If you modify those, you can choose a component that is shared by both of the compsets you want to display, and then you can use the list expression to restrict it to just those two compsets, without displaying anything else.
Then, you'll need to re-design the template you're using for the display of these picks to look one way (adjustable value) when it's displaying an attribute, and another way (fixed value) when it's displaying a derived attribute.
