Add value to existing graphene.Enum

Question

Is there a way to add a value to an existing graphene.Enum?

I want to use graphene-sqlalchemy sort_enum() functionality and to add additional functionality of my own - TOTAL_COUNT_ASC and TOTAL_COUNT_DESC that will enable sorting by total count, but I can figure out how to do it. Directly adding the fields to the graphene.Enum doesn't work:

SqlModel.sort_enum().TOTAL_COUNT_ASC = "TOTAL_COUNT_ASC"

Thanks,

The best way that I found is:

from graphene_sqlalchemy import utils

# Take the original Enum
ExtendedValues  = [(m.name, m.value) for m in SqlModel.sort_enum()._meta.enum]
# Add the new values with EnumValue
ExtendedValues += [("TOTAL_COUNT_ASC", utils.EnumValue('TOTAL_COUNT_ASC', sqlalchemy.func.count())), ('TOTAL_COUNT_DESC', utils.EnumValue('TOTAL_COUNT_DESC', sqlalchemy.func.count().desc()))]
# Create the extended graphene enum
ExtendedEnum = graphene.Enum("ExtendedEnum", ExtendedValues)
