How to move the pin label location in a schematic?

I'm creating a script that adds instances to a schematic and automatically connects pins to those instances.
I can add pins well with the code I’ve written so far, but I want to change the placement of the pin labels.
When I use schCreatePin, the label justify is set to lowerCenter by default.
What I want to do is:

1. Change the justify setting
2. Move the label's XY coordinates

Could you give me some ideas?

Thank you very much for the great help.

procedure(addpin(pinlist)

let(()

y=0

pinMaster=dbOpenCellViewByType("basic" "iopin" "symbol" "" 'r)

foreach(pin reverse(pinlist)

pinlist=schCreatePin(newcv pinMaster pin "inputOutput" nil list(0 y) "R0" nil nil "signal")

y=y+0.125
