Finetuning and Increamental Training of Rasa trained model

I’m currently training a chatbot for a website and I want to fine-tune it with new data. I’ve tried using the --finetune option during training, but it’s not working as expected. According to the documentation, it’s not possible to change the training data for fine-tuning.

OS: Windows 11 Rasa Open Source Version: 3.0

If you remove the previous data and add new data, you can reproduce this issue.

Is there any other way to fine-tune the model with new data? If anyone has suggestions or solutions, please share them with the community.
