You can select a different file name for each run in your macro
/analysis/setFileName MyFile_run1 /run/beamOn 1000 /analysis/setFileName MyFile_run2 /run/beamOn 1000
Then, in your RunAction::BeginOfRunAction(), you should put just:
G4AnalysisManager* analysisManager = G4AnalysisManager::Instance(); analysisManager->OpenFile();
to use the file name set via a macro.
To avoid re-creating your histograms/ntuples for each run, you should also better create them in your RunAction::RunAction (constructor), and move the line
in the RunAction::~RunAction (destructor). Then the histograms/ntuples will be just reset when executing analysisManager->CloseFile(), which call should be kept together with analysisManager->Write() in RunAction::EndOfRunAction().
