If you import configurations into properties mapper, the order of the configurations in the source file determines the order of the imported configurations in properties mapper.
In theory, you could export your configurations, delete all configurations from properties mapper, change the order in the exported file, and import the modified file again. However, that is very time consuming and error prone. And since you would have to do that each time you add a new configuration to properties mapper, I do not think this is a feasible approach.
