Add capabilities in Calendars to filter by a specific Group and a specific Team

Description - In a calendar, I am wanting to get a time off filter to display only those users of a specific group (not a home group) who have time off. The text code below works in a Time Off report, but not in the Calendar:

EXISTS:1:$$OBJCODE=USER
EXISTS:1:ID=FIELD:userID
EXISTS:1:userGroups:groupID=6310fe8100a21f9f230041ac89a1e37c

Note: within a report there is also an option for otherGroupsNames under columns, but it is not available under filters and is not available in the Calendar at all for some reason.

Why is this feature important to you - This will allow us to create calendars tailored to specific groups within Workfront.

How would you like the feature to work - add filter option (otherGroupsNames) as part of the drop-down for Time Off records in a calendar.

Current Behaviour - not able to filter by specific group in the calendar unless it is a Home Group.
