The presentation feature applies at the same level that you select add to presentation. Any content below that level, e.g. Descriptions below each of Strategy->Overview->Mission is not exported and you have to repeat for all children.
It would be great if Add to presentation could also export all child content as an option.
This would improve workflow.
Thank you for the idea. Given the low volume of support for this idea, we do not have plans to make updates in this area at this time.
