Idea: Fine-tunning loop flow

I've spent a significant amount of time tweaking the fine-tuning process both by tuning hyperparameters and implementing new techniques. In the end most of the code is the same and most of it is glue code that could be described as nodes very much like comfyui does.

The individual nodes that encode images into latents and text embeddings are already there. No sure however iteration could be implemented and if this is something that requires significant code refactoring. Given the flexibility of comfyui and the diverse training strategies and diffusion models available it would be really powerful.

How feasible you think this is? Is this something somebody else thought of?
