I know it is not an ideal workaround but if you switch to single page mode,
Then you can one by one right click each page and Select All and repeat with Copy Selection
If you keep a copy of MSPaint active you can paste each page one at a time and save as an image. This is a method I use daily, so for me it works well to collect single page snippets.
The selection does not need to be a full single page, it could be an embedded image or a choice of area, however it is the historic limitation of windows clipboard that restricts your choice to one page max. You can if necessary increase the MSpaint working area and paste multiple clipboard areas one at a time for say an A3 two page spread.
To always extract say pages 5-7 you can use a command line to print to the windows PDF printer but for variable selections you would need to be much more creative to add an “external” batch file that allows for say “this page I am looking at and the next two”
