Am I missing something or is there no mute button in the game?

Time to time i want to play the game in silence while i listen to music. Currently, to do this, I have to go into configuration audio button and turn off all the 5 different types of sound. then i have to come back and put them all in their original position again. SHouldn't there be a mute button where if u tick it, everything goes to mute? and then untick it, everything goes back to your original set audio? Its quite a hazzle at a moment.
