Fileset customized per customer?

I've got a bunch of generic files with in a directory. Customer subdirectories may contain some, all, or no customer-specific versions
of the same files contained in the parent, e.g.:

     config/ --+
               |
               +-- foo.conf
               |
               +-- bar.conf
               |
               +-- A/ --+   ( <== customer A)
               |        |
               |        +-- foo.conf
               |
               +-- B/ --+ (  <== customer B)
                        |
                        +-- foo.conf
                        |
                        +-- bar.conf

I'd like to say:

     "Copy with filterset overwrite everything in the base config/ directory, but for each file
     in the config/ dir, if there exists a file with the same name in config/${customer}/, then
     use that file instead."

I've done this in a few cases by calculating the resultant pathnames into properties, but the situation
is becoming global. Is there a generic answer to this sort of problem?
