I used to use the shortcut for my power off macro in the 850. Program the macro on the main off button, and then use the shortcut feature to link to the macro on all my device off buttons.

In the 900, you're doing the same exact thing, but instead of using the 'shortcut' feature, you just create a 1-step macro. In the 900 I still create my off macro on the watch, off button, and then create a 1-step macro on each of my device off buttons.

There should be no need to copy a macro and have it duplicated somewhere else. You'd never use that in the 850. You'd use the shortcut feature. Just do a 1-step macro.
