I need help on adding Contents from Content Publishing to an update set including the related list for Schedule content. 

Is there a way to make a modal show up using a link in a content (rich text)? I tried adding an anchor tag to toggle a modal, but it is not working.

I have a task that involves viewing all HR cases, and when accessing a specific record, the attached generated document (e.g., employment certificate, etc.) should be previewed within the ESC portal.
