As a platform admin, I want reusable libraries for announcements and resources, similar to survey libraries, so I can quickly select the right template instead of copy-pasting or storing content on my desktop. The library should allow me to: Choose from pre-approved templates. Choose from my own saved templates. Quickly search and select the right content. Save content as a reusable template. Goal: Make creating announcements and resources faster, more consistent, and easier to manage.
