add a box to middle of organizational chart

[Khoshravan]

I am drawing an organizational chart in PowerPoint. I have one position in
top and three positions below. I realized that I have to put another position
between top single boz and three buttom boxes. I tries but couldn't find such
a command. Is there any to insert a box in between without redrawing? TIA

Start by deleting two of the three to give one over one. Add a subordinate
to the lower box and then two co-workers to the resulting box

deleting means starting from zero. i know that. im looking for a smarter way
to do without deleting.
