In an application that has modules that are laid out the same but have different names, this would save the user from having to map each one.
I have a desktop application that, while the primary application is the same, changes a lot of the component paths depending upon the host system against which it is being run. To be able to map all the components for one application path and then simply copy and paste the whole tree to another application would be PHENOMENAL.
In normal circumstances, I could parameterize the identifying properties by using a project variable but, in this case, the variable value is embedded in a longer string.
