PNG Metadata from source to upscaled?

[gateway]

We are writing metadata to our png files and would love to when using upscaling have that data also copied over. Right now we are having to upscale, then re-open the image with PIL, read the metadata from the source image, then resave the upscaled image with this new data.

example of adding metadata to png files.

from PIL.PngImagePlugin import PngImageFile, PngInfo

targetImage = PngImageFile("pathToImage.png")

metadata = PngInfo()
metadata.add_text("MyNewString", "A string")
metadata.add_text("MyNewInt", str(1234))

targetImage.save("NewPath.png", pnginfo=metadata)
targetImage = PngImageFile("NewPath.png")

print(targetImage.text)

>>> {'MyNewString': 'A string', 'MyNewInt': '1234'}

any ideas if this is possible somehow, we would love to avoid saving the upscale, reading from original with metadata, loading the upscale again and saving the upscale. :)
