Image changing when ctrl click

I really like the new convert image function in Dopus. Right now I use two lister and a preview window in my setup. I then goes through a lot of pictures to convert them to another format(web). I does this by having a lister with thumbnails and ctrl click the ones I like to convert. However, the preview window does not catch this and does not update witch is really a drawback. Sometimes I selects pictures I actually needs to take a closer look at and if the preview window had shown that picture I could just ctrl click again to unselect.

So as a short roundup I would like the preview window to update when multiple select by ctrl click.
