Ability to create extensions using Comfy graphs

[green-s]

Not sure how feasible this is currently but I was wondering if it would be possible to implement the ability to patch the built-in/generated workflows using a ComfyUI graph, as an alternative to the current process of importing the (minimal) one from the Generate tab and having to essentially recreate as many of the existing inputs as you can be bothered to if you want it to look good and be flexible when brought back to the Generate tab.

I'd like to use the built-in generate tab functionality as much as possible, but there are constantly new patches like CFG tweaks and caching methods coming out and it's understandable that you don't want to support all of them, but currently we have to either wait for you to implement them, or write an extension, for which you need to know a bit of C# and spend a fair bit more time than you would slapping together a node graph.

Maybe the new subgraph functionality of ComfyUI could be utilized? We click a button to patch some stage of the workflow, it opens up a subgraph editor with the correct inputs and outputs, we save that and then it's injected into the workflow? Not sure whether ComfyUI currently supports that kind of interaction though, and I'm unsure how you'd handle choosing what to expose to the graph or the ability to add custom inputs.

Just an idea though, maybe for when subgraphs have been fleshed out more.
