Dynamic Text Commentary Integration in Dashboards

I am just getting my feet wet in QuickSight. I would like to create a dashboard of metrics, interspersed with static headers/descriptions, but also allow for the importing of text commentary through a data source. This is not pulling text in for metrics, but descriptions of the metrics for that period, as a commentary. We would like to avoid allowing all of the textual contributors access to edit the dashboards, and would rather supply them with a form to collect their commentary, and integrate it into the dashboards.

What is the best way to accomplish this in QuickSight?

This is not possible currently. I can mark it as a feature request.

Thank you. This would be great.
