Yes, if your questions are in a group (back to back without any space between), you can copy or reposition the entire group in one action, instead of moving individual questions.
If you'd like to copy or move a group of questions:
Hover over the group of questions you'd like to copy or move.
You'll notice a "GROUP X" appear in the top-right of the question group, with three icons.
If you want to move the group, select the move indicator and drag the group to the desired area of the form.
If you want to duplicate the group, select the two-page icon, and the group will copy as a new group below.
