Programming: just one action per button

Why is it not possible to programme one button with two actions?

This is a deliberate decision by Niko. 

User tests have shown that multiple actions linked to one button lead to confusion for the end customer. 

The fact that Niko Home Control places huge importance on user ease and the comfort of the end customer means that each button can only correspond to one action. 

Various controls, however, can be linked to the same action.
