Instead of creating a master page from scratch, you can import an existing page from another presentation and designate it as your master page. This saves time and ensures design consistency if you already have a pre-built layout.
Overwriting existing master page:
If your current presentation already contains a master page, it will be replaced by the imported master page.
Data Providers:
If the imported page uses data providers, these will also be imported into your presentation to ensure all linked content and data function correctly.
