pyside2-uic missing "--from-imports" functionality

I migrate a project from pyqt5 to pyside2.

The pyqt5 script used to convert .ui file to .py file was like this:

pyuic5 file.ui -o file.py --import-from=Ressources.Images

It seem like the pyside2 version do not work:

pyside2-uic file.ui -o file.py --import-from=Ressources.Images 

The "pyuic5 --help" mention this:

--import-from=PACKAGE
                        generate imports of pyrcc5 generated modules in the
                        style 'from PACKAGE import ...'

Whereas there is no mention of this option in "pyside2-uic --help"
