Trouble Re-Ordering Horizontal Hierarchy Chart

Hello everyone, I'm trying to find a better way of re-organizing a horizontal hierarchy, I have not found any other way to do this other than deleting the "old" setup and typing in new information manually.

What I'm Trying to Do:
I'd like to have a quick way of moving sections of the hierarchy to different parents without having to delete / re-type all of the information in each box. In my case, to do something like move "Geo Gun" and its children under "Geo Hull".

Images don't seem to be working, so here is a text representation (off the top of my head): is there a faster way of moving B1 and its child to being under A1 (rather than deleting B1 and child, then adding new boxes under A1 and re-typing the information?)

A0: Master Parent

A1: Bannana
A2 (0): Cost
A2 (1): Weight

B1: Pear
B2 (0): Cost

C1: Kiwi

Any ideas are appreciated.
