Rv30 plus robot vacuume with mop

can someone tell me how to switch on the feature to mop only in the stop position? 
 

This feature was available as I used it however cannot locate the icon unless it got phased out in a software update , however  kitchen mop result is poor without this.

can someone assist? The email assistance ignored my email thread - perhaps something to consider if anyone is considering buying as they have poor customer assistance who can't understand English so well.
