I would like a feature that allows you to change the filename extensions on all session tracks to a different extension, so that the session recognises any files that have been converted.

For example, I have a project session with hundreds of tracks ending in .wav file format. I have subsequently batch converted all of the files in that session from .wav to .flac (to save storage space), but when I now open the session project, it can't find the files (because it is looking for .wav files). I would thus appreciate a feature that allows a batch filename conversion (ie change all ".wav" filename text to ".flac"). Other software I use has such a feature (eg 3D software).

Current process:
• Multitrack session using .wav tracks.
• Window > Batch Process (convert from .wav to .flac).
• Replace the entire project's .wav audio files with the new .flac audio files.
• When I open the project multitrack session, Audition can't find the associated audio files (understandably - they've been changed from .wav to .flac). I understand I can replace all of the files manually, but I would like how to automate the process, as my sessions can include upwards of 300 tracks, and it takes me a very long time to manually locate every single .FLAC audio file.
