Previously you could place a macro on one button and use links to execute that macro from other buttons.

With links gone, you have to copy each macro which means that if you want to change it, you have to go and change each copy of the macro.

However, there is an official "workaround" for creating a single macro that you want to use in multiple places.

Create a new device (now called activity). At the activity level there is a macro that gets executed when you go to the activity (it is in the Actions tab). Put your shared macro here, and REMOVE the jump to the device that was automatically generated.

Now just jump to the device to execute your macro. Because you removed the Jump, it executes the code but does not go to the activity.
