Thanks again, Jim. For the record, in case anyopne else is investigating the topic, my remote app seems to be different, but I was eventually able to get it to do what I wanted. This is running the app on a Nexus 10 tablet... Under "My Tones" there was a "Send to Hardware" option in the top right corner of trhe screen that I was able to use. (I didn't notice that option when running the app on my Galaxy S5 for some reason...)
I also learned that after selecting "Amplifi" under tones, the tones in the different "banks' become visible. I was able to drag tones to different positions in different banks after selecting the icon at the top that looks like a horizontal bar chart.
