Generating cucumber JSON report with unique name

I am using cucumber plugin to generate JSON reports, by default it is replacing the existing report. I want to preserve the results of previous runs to consolidate results across multiple runs.

@CucumberOptions(features = "features/test"
        ,glue="com.automation.cucumber"
        ,tags = "@test"
        , plugin = {"json:target/cucumber/report.json", "html:target/cucumber/report.html"})

Is there a way to append a timestamp in the report name for example report160220201145.json?
