minimize file WITH handlelength?

Hello all,

before posting this as a request I would love to hear if anyone knows of a way to use the “minimize file” function BUT make it leave a little handlelength to the clips/audiofiles. A few seconds would be enough.

As I am having trouble with extended saving times, this would be a great way to get rid of unnecessary audio and still being able to touch the audioclips a little.

Is there anyone out there who knows how to do that?
