Can you be more specific about what you want to wait for and what you want to repeat (and when you want to repeat it)?
The M1 executes rules when there is a change in state of a signal, such as a zone input. So, if you want to wait for something, you need to specify what the event is that you are waiting for. You can also wait for time events, such as a specific time of day, or a certain number of hours, minutes or seconds to pass. The time based rules can be combined with other conditions. That gives you something that you can use to repeat operations.
