Chuck,
There is probably a simple way to do this, but I have been unable to discover it.
If I read the question correctly, what you want to use is the Make Album feature of Qimage.
Select your thumbnails that "qualifies" for the portfolio and Right Mouse click. Select ADD TO ALBUM.
Then click Make New Album. That's all there is to it. Select the Album by the name you gave it, and after RMB clicking on the next thumbnail, ADD TO ALBUM, use SELECT. You will find the images added to the album as you continue to ADD TO ALBUM.
That should do it.
