Time Condition - Rotate Schedule


does anybody know how to create a rotate schedule? I assume I need a custom Time Condition. Let me explain. I want to connect customers with a big problem to one of my engineers. I have 2 engineers, that’s why I need the rotate schedule. I would like to connect to the first engineer during even week numbers, and to the second on the uneven week numbers. And it would be nice if it’s still usable if I hire the third engineer :slight_smile: Does anyone know of such a module? Or what I should do to create such a feature? I’m a complete newbie, but I do have some php knowledge. But I simply don’t know how to start.
