Nested Galleries

Dear M Parker,

thank you very much for this great module.

Going by the description on the module page, I'm not clear, whether the module Field PgwSlideshow is per se capable of supporting nested galleries.
With this notion I mean that a user sets up, say, 5 galleries with Field PgwSlideshow.
Then the user has the option to choose one certain image of each of these galleries and display these images as an additional sixth gallery - this gallery I now call "Gallery of galleries". Clicking on any Image in this "Gallery of galleries" links to the gallery the clicked-on image belongs to in the first place and this gallery is then displayed:

If this feature already exists within Field PgwSlideshow, I would be grateful to learn what I am supposed to do to make it working.
If this feature doesn't exist right now I would like to suggest to include it into the Field PgwSlideshow module.

Best regards,
