Should I add the same attachment before committing to review in future versions?

Our app was once rejected in an old version cause of some attachment missing, after uploading some relevant files to "Attachment" panel and committing again, the app get processed. Since then we add the same attachment before committing to review in every new version.


Our question is, should I add the same attachment before committing to review in future versions? Will our app be rejected cause of the same reason even if we have once offered those files?
