Thanks @jtremblay for reviewing this!
I work with a lot of different HubSpot accounts as a consultant on best practices, training, and implementations. What I’ve had them do is remove that person from the rotation, then give themselves a task to add them back in based on when they’ll return.
From a product perspective, what I imagine a user could do is mark themselves as on vacation via the profile and preferences tab so that if they’re a user in multiple accounts vacation would affect all portals they’re associated with. But that would be the spot I’d look to place it!
