1. Is this request related to a challenge you're experiencing? Tell me about your story.

Currently, we generate the article content through the workflow. We will conduct manual approval for the generated content. If the approval is successful, it will proceed to the next step. If the approval is not successful, we need to start the process again from the beginning. We hope that if the approval is not passed, we can be allowed to customize and input some text, such as suggestions for modification. In this way, the AI can make iterative modifications instead of completely rewriting the content from scratch.
