Sessions & Tracks : Importing and Exporting Session Data : Import Session Data Dialog : Main Playlist Options

Main Playlist Options
In the Import Session Data dialog, you can select from the following options to control how the main playlist from each source track is imported to the destination track in the current session.
Import – Replace Existing Playlists
Imports the main playlist from the source track. When you import the playlist into an existing track, the main playlist in the destination track is deleted and replaced with the imported playlist.
*   
If you select this option and import all of the source track’s attributes, this is equivalent to importing the entire track.
*   
If you select this option and do not import any of the source track’s attributes, you replace the audio playlists while keeping your current mixer settings.
Import – Overlay New On Existing Playlists
Imports the main playlist from the source track. When you import the playlist into an existing track, any existing playlist data that overlaps data imported from the source track is trimmed and replaced with the imported data. Any playlist data in the destination track that does not overlap remains in the destination track.
Do Not Import
Does not import the main playlist from the source track. No audio is imported; only the attributes selected in the Track Data to Import list are imported to the selected tracks. When selected, importing all of the source track’s input, output, send, insert and plug-in attributes is equivalent to importing a channel strip.
