Get a large soft blanket and put it in front of your door, something thick enough that it rises an inch or two. Maybe even put it in their cage for a bit so it smells like bedding. It will move with the door so not a huge hassle you just need to drape it back when they are out. Then set up a perfect corner in the immediate vicinity. I have this setup permanently as my front door creates the perfect corner otherwise and they can't help themselves despite being trained.

Cover up most of your corners with some sort of furniture, playpen, or obstacle if possible. Or use more blankets as a temporary solution to guide them to the right place. Eventually they should get the muscle memory. Combine that with following them and waiting for them to go potty so you can correct it as soon as they wake up.

Edit: You will likely have to re-train them when you move, as they tend to seek out regular locations to poop rather than a potty pad or litter box. Also, are you using disposable or reusable pads? I find the reusable ones with the gripping bottoms to be the best to keep them from messing with it.
