Try using the status icons (colored circles) which you can type a number 1-9 on. Click the character's token who is flying, click the little button that brings up status icons. Click on one of the "color" status icons, like blue, or green. Hold your mouse over the little circle status icon (in the icon pop-up). Type a number with your keyboard, 1 to 9. You want to type with your mouse held right over the circle, then it will display your little red number on the color icon. For example 1 could mean they are flying at 10 feet, 2 could be 20 feet, depending on your needs & your game system. It only displays numbers 1 to 9, so if you need double digits, you would need to use 2 circles (like Blue 1, Green 8, could read as "18" if that's needed).
