Suggestion: Way to suppress warning dialog box when replacing a file in an archive via drag and drop

I often update existing files in an archive by dragging the new version from a Finder window into the open window of the BetterZip archive. When this happens, Betterzip shows a warning dialog box asking if I am sure I want to replace the existing file in the archive. I always want to do this, and the dialog box gets annoying. Could you add a Preferences option to suppress this dialog box?

thanks
