Allow Administrators to Post Notifications and Announcements at Report Suite or Organization Levels
Description - As a Adobe Analytics product administrator for my organization, I currently have to rely on numerous communications channels to update my user base about changes to the product or report suite configuration that may impact their data, tagging issues that may cause data gaps, etc. This is both time-consuming and not guaranteed to reach the occasional user who doesn't engage with our core product support team regularly. I think it would be incredibly useful as an administrator to be able to post important announcements/updates at both the product level (i.e. Adobe Analytics) seen by all users AND at the Adobe report suite level seen only when viewing data in a particular report suite.
Current Behavior - Currently, the announcements and notifications only allow messages from Adobe regarding maintenance, known bugs, outages, etc.
