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 recently solved the problem that I mentioned in my comment using different name mapping configurations. While I still would like to see this feature implemented, the OP could potentially solve their problem in a similar fashion by creating different Configurations for the different modules being tested. Then, in each configuration, just change some of the mapping parameters and then you can re-use the same Aliases. It might be more trouble than it's worth the time, depending upon what the module layouts are like, but this might be a creative workaround.
