Export | Custom Column
This box shows the column(s) that will be included
as custom columns for each clip. The only type of export
file that can currently use this feature is the AVID .ale
export format. Each column name included in this box will
appear as a separate custom column with the export file.

*Note: Depending upon the type of export you are
creating, the Clip Name or Custom Columns boxes
may not be valid options for you. If you drag a
column name over either of theses boxes and the
cursor changes to a circle with a slash through it,
then this box is not a valid option for the type of
export file you are creating.
