Edit ( search and replace ) w/in a notebook

[RADSr]

I have an MV where the SQL is written poorly -- by which I mean that the commas are on the right-hand side of the selected columns rather than justified left.   

Do not try to dissuade me from this opinion for it is intractable and correct   😉   

In any case I'm trying to edit w/ search and replace and want to put a carriage return in and place the comma on the new line so:

===========

select  

this,

and,

that,

=========

becomes

=============

select this

, and

, that 

=================

I'm fiddling about w/ search and replace w/in the notebook  to no avail ( screen cap )  with either /n or /r to swap the column for a new line. 

I can -- and did -- copy/paste the text into Notepad++ to do this, but can I accomplish this in the built-in search and replace functionality?
