I experimented with my "tray in tray" idea and it worked out. I put the tray with the propagation cubes in a bigger tray that I used to use to propagate plants in previous years. I filled the bigger one with water. The water level was as high as it could almost reach the cubes tray surface. Thanks to that the cubes stayed very moist. My tomatoes grow on the south facing windowsill which has a radiator underneath so water evaporates quite fast. This is important to keep sprouting seeds in warmth because it speeds up this process. Unfortunately these conditions caused the drought problem and my cubes with tomatoes used to get dry so often. I was afraid that the water from the container would evaporate too quickly but after 24 hours its level did not go down too much. I did not see any signs of fungus and plants look healthy in their "sponges". They even seem to like these conditions;) I had a little problem with fitting the smaller tray into the bigger one because the bigger one was not wide enough. At the end I suspended the smaller tray between two walls of the bigger one hoping that it would stay in a horizontal position. I will see what happens after a week and will write about it...
