You can set the process name using the start REST API call:
But in the UI, when you click the 'start' button on application to start process, you do not have the option to set the name. As a result the default is used and it is near impossible to distinguish the processes by name as they all have the same name showing in the 'Processes' tab. There does not seem to be any supported method to rename a process instance after it is started.
The only option is to add a 'comment' to the process instance, but this should not be necessary if name can be set on start in UI.
