### What should this feature add?

Just like in Forge, separating the sampler and scheduler into two separate fields would make the process simpler and less cluttered. Invoke is also missing a lot of samplers. Here a few that should be added: DPM++ 3M SDE (very common, not sure why this hasn't been added yet), LCM Exponential/Karras (pls correct me if this is already included) and Restart.
