Cropped images in grid format

Hi!

I’m really loving the plugin. I am creating a gallery of posts with excerpts. Since the excerpts are different lengths, I am using the grid layout to ensure that the rows all line up. However, in grid view the images are all different sizes. In tiles mode, I love that the images are square, but it’s more of a masonry layout. Is there any way to make the grid layout have cropped square images?

Thanks so much!
