Studio’s main tool for customizing a Montage clip is the Montage Editor, which allows you to interact with all the settings a Montage provides. Using the editor, you can add content from the Library, change the background, and edit any text in the Montage. The editor can be invoked from a Montage clip on the timeline of a project by double-clicking the clip or with Edit Montage on its context menu.

A useful trick lets you add timeline clips directly to a Montage clip via the Clipboard. Copy the chosen clip using the Copy command on its context menu or Ctrl+C. Then right-click the Montage clip to open its context menu. Choose Paste to Drop Zone, then choose from the graphical submenu of all the available slots in the Montage to select one as the destination.
