Position of exit portal floor 3 Sikemas

I really am enjoying running the Sikema trials now. Wondering if the exit portal on the third floor can be moved away from the chests? I have accidentally hit that portal while trying to pick up loot from the closest chest several times now. It’s really frustrating because not only do I lose that loot, but I also lose access to the other chests and the merchant…and there’s no way to go back. Thank you for your time and consideration.
