You certainly could do this. This is the most basic form of a universal remote.
However, I would argue that using something as powerful as the MX-890 this way
would be something of a waste.
I would agree, but I think the previous poster's idea was to use this as a means to get me started. It will serve to make the remote functional, and serve to familiarize me with the software. Nothing is better for learning that succeeding, so if I dove into a macro it would probably be pretty discouraging. I have FULL intentions of using the remote exactly as you have described in the end.
