If you STOP, and restart, VP will create a new file from the point at which you stopped.

Yes.
Narration files are shown under the Audio tab. If the recording is stopped, the clip may be automatically placed on the timeline. If not, drag it there. Then drag its right edge to the left to eliminate the unwanted portion.
To continue from that point, close the narration box. Click in the timeline and use this button to place the cursor at the end of the existing clip... 
The next new clip will begin at that point. If it does not, drag it to the timeline. To begin the new clip later, first position the cursor at that point.
Narration files on the timeline can be dragged and trimmed, and are also saved by default to the MUSIC folder on the PC.
