I put as many functions as possible in system macros, especially favorite channels. This way when comcast or who ever changes a channel number in a whole house install I only have to change the one macro and all of the remotes will be undated in one stroke, this is true of anything that is shared through out a home. it also makes programing several different types of RTI remotes easier, as all you have to do is drag over the single fav Chanel macro for that specific box. another advantage is that if you are using an XP8, you can VPN into the project and so long as you don't have to change add or subtract any graphics, you can upload directly to the XP8 or K4, K3  touch panels
