User note copying

Is there a way to copy large section from one  User Note file to another? 

Motivation:

My note file can not be searched without crashing Accordance. I want to copy  fractions of the note file and test whether the different fractions crash. Then I can do a binomial search to isolate what is making the file crash. 

But I don't know how to copy Genesis - Psalms into a new note file, for example. Help!
