Feature Suggestion - Custom Workspace Announcements

Custom workspace announcements that can be pushed to all bases and/or visible at the workspace level. This would be handy in a distributed team / enterprise environment where each team operates in their own base within a single workspace.

Implementation ideas: either in a form of a custom notification event, a popup banner inside the base or workspace, or an Airtable made announcements app (we have third party apps disabled in our environment for security reasons).
