Skipped folder to backup again as retry

Hi, I am using Networker 9.1.1.5,  during the backup few folders are failed to backup. ( backup still running after skipping a few folders) 

There is a message "Exited with exit code: -1, Completion severity: ERROR(50), completion status: failed(1)

is it possible to initiate that skipped folder again? instead of backup the entire save set?
