If it was interesting macro, or any kind of choice was involved (ex. do I spend 100 power to activate the global), then it'd be worth the macro. Meaningful macro/micro adds to the game positively, giving you more to do and more opportunities to git gud.
As is, it's just pointless busywork. 2 Shrines and you just have permanent uptime, there's no choice, nothing interesting about it, no meaningful decisions to make about when to activate it.
It's not a big deal, control groups let me keep my Shrine of Memory or Cultist Masters or whatever up if no one else is doing void manipulation,
