Test Executions - No Test Cycle, how to edit / delete?

I'm using Zephyr Scale Cloud, and have found that if I start a new execution from the Jira Story ticket that's linked to the Test Case, then it's essentially created as an Adhoc execution, not associated with any Test Cycle.

Is there any way to update the executions, so that they can be linked with an existing Test Cycle? Or at least be able to delete any executions that were accidentally started.
