Theme Joomla Extensions

skash replied Adjust module parameters

Yes, that is achievable by setting the module parameter Use Multiple Galleries to No and then you can select the gallery to display in the module parameters as well.

So what you would do then, is to create a new Power Slide module for each gallery you would like to show (selecting the different gallery in each new module you created).
If you get stuck send me super admin details to your site and I will help you get started.
