The [save report to file.vi] in report generation tool always Prompt regardless of whether the file to be saved already exists

[ll cool]

When I was using the report generation tool, I found that when I set the do-or-not prompt replacement in [save Report to file.vi] to true，it still always Prompt regardless of whether the file to be saved already exists.It seems like it creates a temporary file with the same name before saving, so what's the point of this option? And I want to know how to do what it was supposed to do
