Is it possible to switch from stacked to grid gallery style on Montauk template?

Hello talented friends,

Been very happy with my template for quite some time, but there is a major area where it needs improvement - the gallery pages. My Montauk template is currently setup with the grid gallery index page, but my individual wedding pages are in a stacked gallery style. I want to prevent people from having to scroll so much to view each gallery and would like to grid the photos.

Are there any solutions to this without jumping to an entirely new template? If not are there any similar templates with a grid layout gallery?
