Mixdown : Export Audio Mix Options : Import Exported File
 
Import Exported File
The Import Exported File option automatically imports the newly exported file into the Clips List so you can place them in tracks. If your newly exported file is split stereo files (Multiple Mono), they are listed together in the Clips List.
*The Import Exported File option is only available if the target file type and sample rate for the export is the same as the file type and sample rate of the current project.
