Can't find SD upscale.

Since custom scripts are written specifically for Webui and Gradio I figured that's why they are not implemented in the plugin;
however if I were to make one suggestion, the one thing that stands in the way of this plugin enabling 100% of my workflow inside Photoshop is the lack of an SD upscale function. (Not the lossy upscalers in Extras)
In particular the way Ultimate SD Upscale script does it. (https://github.com/Coyote-A/ultimate-upscale-for-automatic1111)

If a custom implementation of that is possible at any point in the future, that would be excellent.
