I wonder that is it possible to assign data to a blank field from a line appeared before in logstash?
I mean there is a csv file, and in this csv file, some lines' date field does not have value because these lines prepared to be the continuation of the first line before them.

I have to assign value which appear in the first line ( 4/1/2020 9:33:50 AM) to second and third lines.
I read this topic and understand assign a specific value to an empty field, but is it possible that to assign a value from the other line?
Or Is there anything you can recommend to me?
