[Plugin: NextGEN Gallery] load multiple galleries dynamically?

Not sure if this can be done, but what I’m trying to do is;

I have 3 galleries (Canvas, Illustration & Walls) I want to display 1 by default and have links for the other 2 to load in place of the first on my index.php template.

For example: Canvas is displayed by default -> when I click Illusration, the Canvas gallery displayed is replaced by the Illustration gallery.

Like how the AJAX pagination works for loading multiple pages for images without reloading the whole page.
Any sort of help would be really appriciated, cheers!
