Getting Serenity HTML reports during execution

Question

I am using Serenity with Cucumber. Here the HTML report created for each scenario is with random string.

My questions:

1. Can we rename those individual html report by scenario name?.
2. Is the HTML report generated right after the scenario is completed? Or after the whole execution?
3. If an answer to the 2nd question is yes can someone please explain the report generation flow?
4. Can we get the result during runtime? Or only at the end of the test run?

My requirement is to get test results parallel as soon as each test/scenario/feature is completed.

Thanks!
