It does appear so, but its not obvious how to use it to my advantage:

    A target entry of the form:


    is a pattern matching rule, in which tp is a target prefix, ts is a
    target suffix, dp is a dependency prefix, and ds is a dependency
    suffix (any of which may be null). The `%' stands for a basename of
    zero or more characters that is matched in the target, and is used
    to construct the name of a dependency. When make encounters a match
    in its search for an implicit rule, it uses the rule in that target
    entry to build the target from the dependency file. Pattern-matching
    implicit rules typically make use of the $@ and $< dynamic macros as
    placeholders for the target and dependency names. Other, regular
    dependencies may occur in the dependency list; however, none of the
    regular dependencies may contain `%'. An entry of the form:

    tp%ts:[dependency ...] dp%ds[dependency ...]

    is a valid pattern matching rule.

Don't know where to go from here....

    all : skls \

        rm -f ${STEPSKL}
        rm -f ${STEPJCL}

    .PHONEY: skls
    skls :

    step%jcl: step%skl
        ./tailor $< $@

    .PHONEY: jcls
    jcls :
            # Ummm

Fools ignore complexity. Pragmatists suffer it.
Some can avoid it. Geniuses remove it.
