[Feature Request]: Add/select generated images from a batch to a queue to be upscaled sequentially

Is there an existing issue for this?

What would your feature do ?

Currently you can only individually upscale an image 1 at a time. I generate say 4 images and go through them to see if any of them are worth upscaling. I want to be able either to click "upscale" and have that image added to the queue or select them and then upscale all the selected ones. I prefer the first method to save time.

Proposed workflow

1. Generate a number of images
2. Click upscale on an image
3. While an image is being upscaled, click upscale on another image
4. Another image is added to a queue to upscale right after
