Peeing in a flat cage?

I've been on a steady progression of getting smaller and smaller cages, and I've finally gotten my first flat cage. While it is by far my favorite cage size to date, peeing is a whole new animal. With my previous cages, I have enough tilt to the cage where I can press down on it and make it into the toilet just fine while sitting, but with the new flat cage, I have to basically bend my body parallel to the floor, plus pushing on the cage, to make it in.

Do yall have any advice for peeing with a flat cage?
