I'm slowly getting the hang of the 810 but the Browser inside Pro Wizard still intimidates me and I sure wish there were instructions solely pertaining to it's use. As it is I've kind of stayed away from using it fearing I could mess up my work but on to my question.

If you want to change a function on a lcd button of a device the software lets you go into Tuneup and learn a new command to it but it only changes that command in your Devices, it there anyway to also change that function on that Device in a activity? It seems like you have to redo your activity to make that change or will the Browser somehow let you do it?
