In perforce (PV4) how do I see all the check-in comments for a file including comment on other branches that have been merged in?

I wish to see the comments on all check-ins (change list) that has effected a file, including any check-ins to a different branch of the file that has since been merged in.

(Ide开发者_开发技巧ally I would like to filter out any comments if the only operation they relate to is a branch or none conflicting integration.)

On the History tab, there is a button that allows you to display branch actions.

I don't know of any way to filter out submissions that were simply a branching operation.
