ValueError: WD_PARAGRAPH_ALIGNMENT has no XML mapping for 'start'

Is it possible to add on existing (left, center, right) the start and end mappings so that this error is avoided. If I'm correct it should be added in the

class WD_PARAGRAPH_ALIGNMENT(BaseXmlEnum):    LEFT = (0, "left", "Left-aligned")    """Left-aligned"""    CENTER = (1, "center", "Center-aligned.")    """Center-aligned."""    RIGHT = (2, "right", "Right-aligned.")    """Right-aligned."""...

like

END = (0, "left", "Left-aligned")

or

LEFT = (0, "left", "Left-aligned", "start")
