Add new missing segment to existing failed idocs

Hello Experts

1000's of idocs have failed due to missing child segment. i can add the missing child segment & data in WE19 & reprocess the newly created idoc(copy of old) which works as expected, but i have to do this one idoc at a time.

Question: is there a way, i can do this across multiple idocs at once, like mass processing?

Thanks in advance for your quick responses.

Thanks
