Hi Reji,
The best way to do this is using H9 Control. When you open up the app, go to the bottom where it says “Lists.” Go up top to where it says “more” and click on “New preset list.” Populate the preset list with your favorite sounds. Repeat this process as many times as you want, just make sure you’re naming the lists so you know what kind of effects are in each one. In order to download the list to your pedal, you have to click the “to pedal” icon up top. It will give you the option of only showing you the number of presets on you lists; otherwise all other preset positions will stay the same and only the new presets will be overwritten. For the most in depth look at preset lists, check out this video:
