How to implement "Upscale 2x" in Comfy Workflow

[FireCosmos]

I really like the "Upscale 2x" feature in the generate tab of SwarmUI. It uses the prompts given to upscale the image 2x. However, I can't find out a way to exactly replicate the feature in the Comfy Workflow - The import from generate tab doesn't import this feature.

that is a legacy feature that literally just inserts the image as an init image and sets the resolution to double, it's largely deprecated in favor of the refine/upscale params

[FireCosmos]

But it doesn't just double the resolution it also regenerates the image at a much higher quality visually which I'm interested in replicating

[mcmonkey4eva]

yes

[FireCosmos]

What's the best way to that in Comfy Backend?
