Merge consecutive log lines with same timestamp

[mbhegde-orcl]

I have a tail log source.

there can be multiple lines with same timestamp, I want them to appear as same log for my use case.

As I understand, multiline parser needs a regex to find the start line and continuation lines of the log. But how can I say "merge line B with preceding line A if it has same timestamp, else start a new log record"?

Eg: First 2 lines should end up as same log record and the 3rd line in separate log.

2024-10-21T04:51:20.530410405Z Here's some detail
2024-10-21T04:52.28.340033380Z Here's something else

is it possible using filters or some other settings? Apologies if I missed something obvious

Thanks
