Loop marker in audio lab?

[fycfung]

Forgive my ignorance, but I was wondering: is there (or should there be) an analogue of the loop marker in the audio editor? That way, we can truncate a sample in the editor? Or is there some other thing I should be doing?
Thanks!

No, currently you can only define a Start point in for an Audio Part.

The Audio Part's end defines where the audio stops.
