Hi Peter,
David has mentioned the options. I personally prefer to setup a plan. I do the composition in the sky atlas module and once happy with the framing, create a plan which then sets the coordinates etc. Then every night you just resume/start the plan with a click of button. That's all you need to do.
If you need to make changes to the plan, e.g., reshoot a specific filter due to clouds the night before, you can reset the plan and adjust the number of frames, plan settings etc.
Here is a quick example with a mosaic:
