when migrating from avid to Pr, how to stop generating "recovered clips" and other footages

I migrated some avid aaf files into Pr. It automatically generated a bin with all sequences I need, and with video clips, and a "recovered clips" bin containing some audio files. These clips are already exist in the project.

It looks similar to importing a sequence from another Pr project. In Pr, I could choose not allow duplicate files. In this migrating process, is there any method to avoid these duplicate files?

Thank you!
