Task planing, how would you do this?

[Stereomike]

I want to execute a certain template (1) three times (all at the same time, so it would be 3 instances).
After all three template-1 runs, I want to execute template 2

Then it should start over with doing 3 times template-1, followed by template-2.
repeat...
repeat..

I can group things, but how do I loop in the task list?

I'm not sure if I understand - but perhaps you could use "system of schedules" - load your task there with grouped templates and "assign task repetition". It should do the trick.
