That is precisely how the [_], [^] and [$] operators work.

>From the man page:
       There can be several instances of setting the default/prepend/append
       values in the configuration file. The later setting replaces the previ-
       ous one for the rest of the configuration file.  The
       default/prepend/append values used for a given keyword/target pair are
       the ones that were in effect at the point in the configuration file
       where the target was mentioned for the first time.

       Example:

        MaxBytes[_]: 1250000
        Target[myrouter.somplace.edu.2]: 2:public at myrouter.somplace.edu
        MaxBytes[_]: 8000
        Title[myrouter.somplace.edu.2]: Traffic Analysis for myrouter.somplace.edu IF 2

       The default MaxBytes for the target myrouter.someplace.edu.2 in the
       above example will be 1250000, which was in effect where the target
       name myrouter.someplace.edu.2 first appeared in the config file.
