Is there a way to access / override the USD Layer editor buttons from python ?

[voidreamer]

Hi, I really like this UI, is there a way I could override what the save button does ? so I bring different options / constraints when I want to save ?
thanks

import maya.OpenMayaUI as omui
from shiboken2 import wrapInstance
from PySide2 import QtWidgets, QtCore

usdLayerEditorView = omui.MQtUtil.findControl('mayaUsdLayerEditor')
usdLayerEditorViewPtr = wrapInstance(int(usdLayerEditorView), QtWidgets.QWidget)

def customFunction():
    print('test')

for buttonn in usdLayerEditorViewPtr.findChildren(QtWidgets.QPushButton):
    if buttonn.toolTip().lower() == "save all edits in the layer stack":
        buttonn.clicked.disconnect()     
        buttonn.clicked.connect(customFunction)
