changes package for peer reviewed journal: hide authors and convert 'replaced' to 'added'

I'm using the changes package to keep track of any changes I ( and my co-authors ) made for a peer reviewed journal. Meaning, in response to each of the reviewers' comments, we are using a new author id from the changes package to make it easier (for us) and the reviewer to find our additions and changes to a specific comment. But moreover, we also use a special author id to keep track of linguistic/grammar corrections we made.

1. 
   

   But now, when submitting the revised journal, we would like to hide all linguistic/grammar corrections we made ( just show the 'final' state ) to avoid too much different colors and confusion. How I can 'toggle' the 'final' command for specific author id or achieve something similar?

   Also I would like to replace all \replaced commands by \added to hide the crossed out text. How can I do this?

   
   

\documentclass{article}

\usepackage{changes}
\definechangesauthor[name={Reviewer 1. Comment 1}, color=red]{r11}
\definechangesauthor[name={Reviewer 1. Comment 2}, color=red]{r12}
\definechangesauthor[name={Language/Grammar}, color=black!50!green]{lang}

\begin{document}

Bla bla bla \added[id=lang]{blubb} bla bla \replaced[id=r11]{addition}{Bla}.
