WHD Ticket "Flag" Feature

Folks - A couple of questions:

1. Is there a way to enable the "Flag" feature to be seen by multiple techs across multiple tech groups?

I would like to be able to use this feature as a way to communicate with my Techs regarding "follow up" without needing to change ticker priority.

2. Can the "Flag" feature be set to be "unflagged" when the ticket is closed?
