Expand TinyMCE for Mass Mailer?

Is there a way to expand TinyMCE for Mass Mailer?  I would like to use HTML, color, image, etc etc.  The same stuff we see in Page Builder.  

It can be done since I've done it.  As I remember, you need to switch code from "mini" to "full" editor (or something along that line).  I will check later if no one offers an exact solution... when I return.

go to administration/notifies.php at line 194

change

'html' => 1,

to

'html' => 2,

done.

simple :D

Thanks guys!!  I appreciate your help!  :D

Where is this done in 7.1?

I just went to the mass mailer on my site and it appears to be using the same TinyMCE as the blog post editor.  I am seeing the additions to the toolbars that I made to the blog post editor.
