Scheduled tasks dependencies

Hi

I have a simple question. I have a large vm and I want to create one or more scheduled tasks that does the following:

1. shut down the vm
2. clone the vm
3. power on the source vm
4. e-mail me when it's done

Is it possible to have some sort of dependencies on this? Like: "when shutdown is complete, start cloning" and "when clone complete, power on source vm".

I know how to manually create all these schedules, I just want it automated so that I don't have to pay attention to it "all the time"...:-)

By the way, this is on a v5.5 environment
