Google Calendar API - Group Attendee Emails

Question

For Google Calendar API v3, is there a way to expand an Attendee Group so that when the API returns a Calendar Event object, it returns all the Attendees in that group instead of simply returning the "group" as an Attendee.

Currently, if I invite a Group (i.e.: All Staff), the API returns the attendee group as if it was a single attendee.

<Google::Apis::CalendarV3::EventAttendee:0x000000000292b3f8 @email="[email protected]", @response_status="declined", @display_name="Attendee One">, 
<Google::Apis::CalendarV3::EventAttendee:0x00000000028d0b88 @email="[email protected]", @response_status="needsAction", @display_name="All Staff">]

Instead, it would be more useful to expand the group and output all the attendees and their respective responses.

<Google::Apis::CalendarV3::EventAttendee:0x000000000292b3f8 @email="[email protected]", @response_status="declined", @display_name="Attendee One">, 
<Google::Apis::CalendarV3::EventAttendee:0x000000000292b3f8 @email="[email protected]", @response_status="declined", @display_name="Attendee 2">
<Google::Apis::CalendarV3::EventAttendee:0x000000000292b3f8 @email="[email protected]", @response_status="needsAction", @display_name="Attendee 3">
<Google::Apis::CalendarV3::EventAttendee:0x000000000292b3f8 @email="[email protected]", @response_status="attending", @display_name="Attendee 4">

Update: Google Calendar API does not currently support the functionality to expand Attendee Groups to add individual attendees within the group as Event Attendees.
