Possible to have different settings on across multiple portfolios?

I am creating 5 separate portfolio pages (3 are currently live). Four of them should have 3:2 aspect ratios but one of them needs to have 2:3

Portfolios with 3:2

• https://www.danwrightphotography.com/performing-arts
• https://www.danwrightphotography.com/bands

Portfolio that I want to have 2:3

• https://www.danwrightphotography.com/red-carpet

Right now I've basically done a crappy/hacky version of the red carpet portfolio where I just added white space to the sides of the photos to make them 3:2 so nothing got cut off. It looks awful though so I'd love to not have to do that.

You can add this code to Design > Custom CSS to change to 2:3 on red carpet page only

body#collection-647d3b01b5f88c34f39cd386 {
.grid-image, .grid-item {
    padding-bottom: 150% !important;
}}
