Merge newer version of processes into existing process
For an example, I sent one of my processes to Professional Services, he edited the process, and then when I re-imported it, it was a totally different process and I had to edit all my other processes that pointed at the old process to point at the new one. If I could just merge the newer prp file into my existing one (basically just adding a newer version in the History), it would save some time and effort whenever we have to share out our processes.
Kindly note that you do not need to edit all the processes that point out to the re-imported process. Simply place the new process where the old one is and give it the same name (after renaming the old one).
Also note that when you export a process its commit history is exported as well.
