karate-gatling report aggregation

Question

One question as just starting to use karate-gatling: is it possible to aggregate the reports generated? So after multiple runs to get one single report? It would be nice to be able to compare somehow the performance - to get automatically the information if there is a performance degradation or not. What I did try but did not work, was to copy the simulation logs and afterwards only generate the reports ("gatling.bat -ro simulations") but this did not work. The error that I got was: gatling.bat -ro simulations/catskaratesimulation-1544015145031 GATLING_HOME is set to "D:\\AutomationTeam\\gatling-charts-highcharts-bundle-3.0.1.1" JAVA = ""C:\\Program Files\\Java\\jdk1.8.0_131\\bin\\java.exe"" Parsing log file(s)...

Is there another way to do it? Should I somehow reconfigure gatling? Thanks!

通过gatling.bat -ro folder_with_simulations使用相同版本（2.2.4）时，它可以工作。
