Provide original hammer events to the user

When I use 'rangechange' ,'rangechanged','timechange' or 'timechanged', I want to get the hammer event object like I want to use pannleft or panright, sometime I need the delta. I have change the code like

 this.body.emitter.emit('rangechange', {
      start: startDate,
      end: endDate,
      byUser: true,
      originEvent: event
    });

Will vis add this feature?
