OnDemand users are not able to create user macros. However, Atlassian recommends in their documentation to use a NoPrint macro to create content that should not be in an export.
The export to PDF option is used often for creating customer-facing documentation. However, not having the noprint doesn't allow a write to keep content together, with some content only pertinent for employees such as configuration, support, or implementation teams.
Not having this requires us to create and maintain separate document which disrupts the flow and can be confusing.
It would also address the current issue with the NoPrint attribute on the TOC being broken. We use the TOC often to assist with online navigation; but, it is not always appropriate to have this in exported, client-facing documentation. This would provide a workaround for this current bug.
