If you have Sub-showrooms and you'd like to make a presentation from the Master showroom available to them:
1. Open the Presentation's Share Settings
2. Under the Share With dropdown, click "Sub Showroom" dropdown to manage this:
- None (default): Not visible in Sub-Showroom
- Team: Inside Team
- All: Inside & Outside Team
A presentation shared from a Master showroom will now appear under the "Shared" tab on the sub showroom.
