I want to Pay for Storage only! - PLEASE!

I’m currently taking a year break from personal projects using Adobe Express Premium, but because I’m using 5.8GB storage, I am now going to loose ALL of it, due to downgrading to the free version. 

Please make it possible for us to pay for storage only, without having to pay $15 a month for Premium. 

Even if I go through all my images, It’s going to take me forever to delete 800mb, as all my images are around 1-2mb each!! It’s a complete nightmare! I’m starting to really regret using Express. I wish I bought a standalone program instead, as now I’m tied to paying Premium for life or spend hours going through 800mb worth of images. :(
