"Enable customization when weapon is drawn" is the option you want. Only tick set 1 and 2. Do the same thing to the option above if you dont want to differentiate between having your weapon out or not.

If you have the top option set to 3 and 4 and the weapon drawn option to set 1 and 2, you will be scrolling between 3 and 4 while you're out of combat and scrolling between 1 and 2 while you're in combat.
