ASK-SDK Python - How do I use multiple permissions in ASK-SDK simultaneously (i.e. reminders and postal code)?

Essentially, I have a skill which already has code for reminders in it: and to check for permissions and ask for them I have the following code:

        ...        permissions = request_envelope.context.system.user.permissions        if not (permissions and permissions.consent_token):            # No permissions exist - ask for them            logger.debug('Reminder permissions not yet granted')            directive_response = handler_input.response_builder.add_directive(                SendRequestDirective(                    name="AskFor",                    payload={"@type": "AskForPermissionsConsentRequest","@version": "2","permissionScopes": [                            {"permissionScope": "alexa::alerts:reminders:skill:readwrite","consentLevel": "ACCOUNT"                            }                        ]                    },                    token="reminder"                )            ).response            logger.debug(directive_response)            return directive_response

request_envelope.context.system.user.permissions (I logged them):

Directive response:

{'api_response': None,'can_fulfill_intent': None,'card': None,'directives': [        {'name': 'AskFor','object_type': 'Connections.SendRequest','payload': {'@type': 'AskForPermissionsConsentRequest','@version': '2','permissionScopes': [                    {'consentLevel': 'ACCOUNT','permissionScope': 'alexa::alerts:reminders:skill:readwrite'                    }                ]            },'token': ''        }    ],'experimentation': None,'output_speech': None,'reprompt': None,'should_end_session': None}

I notice that the following code doesn't actually check for the reminder permission specifically, only that any arbitrary permission exists. Now, this would be completely fine in the absence of other permissions, but I am looking to use the postal code permission also - how would this work? My first thought was to use the consent_token in the permissions, but that comes without a key for a token/permission name, and it doesn't come with the response, so I have no way of knowing which consent_token is for which permission. Is there any way to get this working? Help would be much appreciated.
