UART serial connection

I’m working on a project that would use all ten available presets. The analog key input only shows 4 available. I could send the commands through the IR Input, but there are only 6 available. It seems the only way to active all 10 is through HTTP API. I will be using Arduino to send the preset commands, is there a future serial connection planned or are there more IR commands available to get the 4 remaining presets?
