Move AIP sublabels to a different parent label

pheeeling 

you can make a sub-label > parent label (with no sub-labels)
move sub-label to another parent label remove all sub-labels from a parent label, making the original Parent label a normal label without sub-labels and therefor selectable as a label either manually or via auto-labelling client side rules.

example: make sub-label a top level label
set-label -identity nameoflabel -parentid $null

example: move label above to another parent label
set-label -identity nameoflabel -parentid <immutable of parent label>

To make a existing parent label selectable as a label with no sub-labels you simply need to run the first command on each of the exist sub-labels.

for all of the above you first need to connect to SCC by connect-IPPSSession

you can check the settings before and after by running

(get-label nameoflabel).settings
