How to make image plugin automatically set filename as title?

[SageJustus]

export const sageImagePlugin = imagePlugin({
  imageUploadHandler: async (image: File) => {
    console.log(image.name)
    return FileUtils.convertToDataUrl(image)
  },
  imageAutocompleteSuggestions: ['https://via.placeholder.com/150', 'https://via.placeholder.com/150']
})

I didn't find a place to set it. imageAutocompleteSuggestions can only accept strings, not functions with file parameters.
