How do I distinguish between two pending change lists in perforce?

I have several similar pending change lists, based on the top of the code branch and the same workspace in perforce I need to distinguish between them and (eventually) merge them into a change list What is the fastest and easiest way? I'd rather avoid creating a temporary branch

Solution

The latest version of the server supports canceling changes to the workspace of open files and solving the merge problem

So, assuming your server is new enough, you just need to:

>Shelve changes > start with a clean workspace > cancel changes to one of the workspaces > cancel keeping other changes in the same workspace > resolve any resulting merge changes. > Carefully check your differences before submitting to ensure that you have the required changes
