You don't need to throw everything out, either.

Duplicate the canvas (this way you have the original just in case)
In Canvas 1, delete layers 2 - 20
Duplicate Canvas 2 as Canvas 3
In Canvas 3, delete layer 1
Duplicate Canvas 3 as Canvas 4
In Canvas 3, delete layers 3 - 20
In Canvas 4, delete layer 2
Duplicate Canvas 4 as Canvas 5
In Canvas 4, delete layers 4 - 20
etc.
