Dify version

0.15.3

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

In the file question and answer, the file content uploaded by the user needs to be analyzed, and then the file content and user questions are spliced, and finally sent into the large model, this time the input of the model is file content + questions.
However, I found that dify's conversation history only records the original user input + model output, which causes a problem that the model cannot see the contents of the file uploaded by the user the next time the user asks.

I know that a process will involve multiple model processing, may be more difficult to achieve this function, if you can rewrite user questions, this should not be prone to bugs

I now want the conversation history to remember these processed inputs. What are some ways to do that?

✔️ Expected Behavior

User questions can be rewritten, and the model memory stores the rewritten questions

Actual Behavior

No response
