Currently there is not an option to customize the columns in the test cycle summary. However, we will add this to our feature request list. Our feature request list is important becuase our product team reviews it when creating a new release.
We have added a Knowledge Base Article to our database that may help some users with modifying the columns of test executions. Please see the link to the article below and let us know if this helps or not. Any feedback is appreciated.
