I only know how to do it on an iPhone. Go to settings, then general, then keyboards, then text replacement, then hit the plus sign.  You can add a short easy-to-type phrase in the first box (like Ddd for me) and then the $100 DEGEN in next box.  When you type your shortcut in the app, it’ll fill it automatically.
