HiDream Sampler ADV input options and system prompt

[phazei]

I looked at your node, and it has a lot of features I'd like to try.

Currently I'm using the comfy core KSampler and a quadClipLoader and it's working pretty well. I'd be nice if your node could allow inputs so we can select our own LLM model and our own HiDream model.

Really what I'd most be interested in is being able to adjust the system prompt, and I don't know of any way to do that other than the input I saw on your node. Perhaps there could be a new node that can take in the model and let us set a system prompt?
