Lightroom for mobile: Square thumbnails

I would love a view option to show thumbnails as squares (cropped) in Lightroom for mobile, instead of showing thumbnails with the images' true aspect ratio. As it look today on my phone, portrait photos sometimes get so small that it is hard to see them when scrolling through my photos. With square thumbnails, each image gets the same amount of screen real estate in the thumbnail overview, regardless of whether the image was a portrait or landscape oriented photo.
