Transient Stretching not saving

I stretched some audio using the "Stretch to" command under Audio Transients.  When I reloaded the project, none of these changes had saved.  Do I need to use the AudioSnap Render feature to apply and save these changes, or is that just for audiosnap?  I read that the only solution may be to bounce the clip.  I am hoping this transient stretch data can be saved with the project.  Using X1 expanded.
