Work With App option to allow gpt modify things without the need to copy

I genuinely enjoy working with ChatGPT on my applications, but I feel that its integration is lacking. Currently, I have to manually copy and paste the code, which is inconvenient. I would greatly appreciate it if ChatGPT had a button that could ‘intelligently’ add the changes I requested. Additionally, it would be beneficial if ChatGPT could create files, replace code, and modify (some) settings.
