Dear @Mirtaaa,
It appears you wrote an answer that you would not implement this feature as other things are more important for your business. I understand that.
However, it seems there is a misunderstanding. As Zammad is developed as an Open Source software, I understand that you are open to contributions from the community. In addition to the feature request, we offered to implement the optional functionality and propose it to you as a Pull Request. If we put some effort into the implementation, is there a chance this will be merged? It would avoid hassle with local modifications and reduce the necessity of forks.
