Grouping conditions in workflow designer

Currently is not possible to group conditions in the workflow designer when using the SmartObject List method. This was possible in Blackpearl (https://help.nintex.com/en-US/k2blackpearl/userguide/4.6.10/SmartObject_Filter_-_Using_List_Method.html) but unfortunately not in K2 Five. It would be very useful to have this feature.
