Read PNG info of file for img2img or inpainting prompts and settings

It would be nice if there were a way to input a PNG file to read the stored generation info to input into the UI. I often go back to images I've generated in low resolution in order to upscale them, and I use the same prompts I did the first time. I drop these into Auto1111's PNG info tab, and then send it to img2img. That fills out the prompts, and sets up all the settings the way it was when the initial generation was done. But there isn't a way to do this in the plugin. I have to copy and paste the prompts, and all the other settings.
