[Announcements] Send Announcements by Differentiation Tags

[jfountain]

Problem statement:

We're loving the new Differentiation Tags feature and look forward to how it evolves. We'd like the ability to send course announcements by tags instead of only by course section.

Proposed solution:

Include the ability in announcements to send to sections AND/OR differentiation tags. Ideally, we could still limit the announcement to section(s) but further limit it to students with certain tags in those selected sections.

User role(s):
