There are a few options available. I would check out FlashZebra, as he knows some of the nuances of how these work with various flashes.

You can also get a CSRB receiver and connect to the speedlight for triggering with your CyberSync system. If you have a Cyber Commander, you can use a CSRB+, and meter and group the speedlight (but adjustment will still be made on the flash itself).
