Sometimes I create a quick mix of only the solo section of a tune with a fade in/fade out for a small mix to present to a guitar player and get their thoughts on the vst plugins and efx:     I might send them a few mixes from this area of the project with different plugins.  Usually I erase this fade in/fade out after I do the temp mixes.  Is there an easy way to save and then later get the envelopes back in the same position sometime in the future in case I need to do this
