Optimize/Truncate/Delete Unused Samples

[MIDI Life Crisis]

In examining my MachFive samples, I noticed a fair number of unused audio files and a lot of silence in other (used) audio files. Most are in my own custom samples, so I am guilty of not truncating them at the time of creation. But does anyone know if it is possible to process samples on a more wholesale level?

Ideally, I would like to be able to tell MachFive to delete unused samples and truncate to only used portions of samples. Any ideas?

TIA.
