Custom EQ on Fiio KA15 on iPhone

[Ottomatic]

Hi everyone, new user, first post.

How do you add user-created or "recommended" eq presets to the KA15 and have them saved when you use it on an iPhone? I connect the KA15 on my PC to the web interface and add them, but I can't find the presets later when I connect it to an iPhone.

Can anyone help? Thanks!
