[WP Smush Pro] WP Smush Pro > Resize Image Only Before/During Manually Smushing

Hi,
in WP Smush Pro, I set "Resize my full size images" to "2048x2048" and no "Automatic Smush on upload" to "off".
Now I realize that images are resized on upload.
But I want images to be resized only during smushing (which I do manually by click to "SMUSH" button in Media Library).
Please how to do it?
Thanks,
Jiri
