Hi MWilliams!
I'm glad you're using this feature.
Currently, the "recurring" option is only available for creating projects. However, we keep on updating our features, and we hope this will be available for creating client requests as well in the future. You can check more about this feature in this article: The Practice Management feature.
If there's anything I can help you at the moment, please don't hesitate to go back to this thread.
