Why cant we change pictures?

I love the app, but I think we should be able to change pictures for Loops and Tracks. For example, if you wanted to put a Synth track and just call it a Piano track, you should be able to change the Synth picture to a Piano picture instead of having that annoying FX thingy picture. Its just something to think about, but I really think this is becoming an issue and it should be changed. Thank you for considering,
Zack
