Is it possible to attach a custom file in the @After method to the serenity report

[zarduc]

Hi all,
I am using Java, JUnit and Cucumber to run all the feature files in /features parallel.

` import org.junit.platform.suite.api.IncludeEngines;
import org.junit.platform.suite.api.SelectClasspathResource;
import org.junit.platform.suite.api.Suite;

@suite
@IncludeEngines("cucumber")
@SelectClasspathResource("/features")
public class CucumberTestSuite {} `

The serenity (4.1.12) report already contains the screenshots.
Because the logs in Jenkins are mixed up due to parallelization I would prefer to attach a file (.txt or .log) to the serenity report.
Is is possible to attach the file for each feature to the Test Results:All Tests view (see screenshot)?
Is it possible to add a custom column without custom implementation?

Or somewhere else without doing that in a Step? Is it possible to do it in @after method?

FYI: it's not the same file, separate file for each test.

Thanks in advance.
