Add CLI command to replace existing checkin-comment
Via GUI it's possible to edit existing checkin-comments and save them.
In the CLI (cm command line) there is no equivalent to this action. There should be a command to replace the comment of a specified changeset.
That way we could apply batch pattern-replacement in checkin comments, similar to "git filter-branch --msg-filter". This is not about rewriting history, as only the comments will be modified.
An example of where this is useful: after import from SVN via Git each changeset has got an appended formatted string, starting with "git-svn-id:" and containing info about the corresponding branch and revision in the original SVN repository. It would be very nice to be able to batch-process this formatted string into something more readable without having to do it during the actual migration.
Additionally, in Plastic there are ways to add auto-comments on checkin. Whenever we have a formatted string that can be pattern-matched and that is automatically added to each commit, it will be useful to be able to post-process those.

This would be a big help for our use case too - looking up data from other databases based on user-entered codes to pull in checkin comments from other sources

The cm command should be able to do anything the GUI can do.
As near as I can tell, cm *is* the api for Plastic. The api is incomplete.
This is not the case for Perforce p4 or p4api.

Actually the command could probably be used to change comments of any object, like branches, labels and so on.
Interesting but not high prio, I'm afraid.

While it _is_ possible to achieve this via "advanced queries" and "execquery update" it's not recommended... There should be a CLI command for this since it's already doable in the GUI. Suggested syntax:
cm replacecheckincomment | replmsg cset_spec new_comment
cm replmsg cs:85 "Testing the new replace comment feature"
