Hiding some options values in CU50

Hi,

How can hide some options values in CU50 for some cases ?

For exemple with a car which has some caracteristics :

The motor caracteristic has 4 options values possible : economic, standard, confort, sport

The shock absorber has 4 options values possible : soft, normal, hard, very hard.

I need to configure sap in a way that if the motor caracteristic selected in CU50 is "sport", there are only 2 options values which will appear in CU50: "hard" and "very hard". This means that soft and normal will be hidden in this case.

Thank you
