How to change collection pages to have separate pictures

[Downbadmerch]

I have a page on my website that shows collections for products from different artist. I added a picture with text to the default collection and wanted to change it to a different picture for the second artists collection, but when changed it affects both spots. what would be the best way to go about making each collection page unique to have a different picture and text on the page while using basically the same layout? here is also the link to the page so you can see for yourself: https://downbadmerch.com/collections/niko https://downbadmerch.com/collections/ree0

Nevermind figured out how to change on the collection page to a different collection template and just copied the default page each time and made a separate one for each
