New Post: Custom toolbar for single instance of

I was unable to customize toolbar sets for one of editors instance in my module via JS

 CKEDITOR.replace('dnn_ctr476_View_TexteditorThumb_TexteditorThumb',
       {
           toolbar: 'Image'
       });

toolbar with Image is showing correctly, but inside Image configuration is different - without File Manager integration (image selection button is missing).

Is other, better way to setup different toolbar set on different editors instances on single module?
