Auto Rotate, ability to mark user as on vacation or sick to remove/skip them in workflow

We NEED this! Our sales team is growing and this is already becoming a big pain. We want to make sure our valuable inbound leads aren’t sitting in someone’s inbox when they’re out on vacation. It would be great if there was some way they could mark themselves as unavailable within a HubSpot “calendar” or if it worked like the chat/conversations feature where they can choose when to be online or offline.
