ogrish on "[Plugin: NextGEN Gallery] Random gallery preview imagelinks in an album?"

I like NextGenerationGallery thank you for creating it.

Now I have a question: If I want to display galleries in album with number x I write shortcode:

[ album id=x]

I will then get imagelinks with preview images of each gallery in album x.
How about if I dont want to display gallery preview imagelinks of all galleries but only a subset of them for example 3 galleries of 30 galleries in an album is there a way to do this? Like

[ album id=x include_gallery="1,2,3"]

or

[ album id=x exclude_gallery="1,2,3"]

I know there is shortcode to display random images from a gallery. Is there a shortcode to display a random subset of gallery preview image links in an album?

Say I have 30 galleries but I want to display preview image links to 3 random galleries. How do I do this?

Thank you for your answer.
