After scanning the first tissue perform these steps to add another tissue to the virtual slide:
00. Click "Add new sub scan" or press"F" to enter Freeze-Mode.
01. Now all image content that is already scanned is frozen.
02. Move to the new starting location on the physical slide.
03. Use the mouse to drag the already scanned data away until the specimen visible on the camera is approximately at the same location relative to the other scanned specimens as it is on the physical slide. You can choose other locations freely, but you should take care to avoid overlaps between the old and the new scan on the virtual slide.
04. Press Enter to start scanning or press backspace to undo freezing
