Personal Contacts Groups and Time Away Status

[JFenton]

Hello,

1. Is there a way for individuals to create personal groups in their individual contacts lists (not in Teams Chat)? For instance, could I go into my contacts list and create a group for the Marketing Team, that only I would be able to see?
2. Is there a way to time Zoom presence? Ie, how can we tell how long someone has been away/unavailable? If Zoom does that have this functionality, is there a third-party app that could be integrated with the Zoom client?

Thank you!
