Translate project with AWS translation service on pipeline

I have content wrote in two languages. Currently I translated output to other languages with some script using AWS translate service. But then I'm not able to use search funcionality which I need to have also in translated output. When I'm trying translate project with built-in feature it takes a lot of time and every changes needs to be marked to be translated manually after each change. Could it be done somehow better? For me best option is translate projects using some calls via cmd in pipeline. Can I create translated output somehow automaticaly? Currently I'm building output in that way: 

call %RH_Base%\watcher.bat "'Project.rhpj' Project" %RH_CMDUtility% --cl "%RH_BasePath%\Project_Total\Project_Total.rhpj" -o %RH_Preset% -l %RH_LogPath%\Project_Total\output.txt -p %RH_OutputPath_Project_Total%\en
