How to get the second dependency file using Automatic Variables in a Makefile?

I need to get the nth dependency file from a rule, something similar to $n in bash. I need this because I'd like to feed in individual dependency files as options to the build program.

Here's an example:

dep.o: dep.src config1.cfg config2.cfg
    parse -cfg1 $2 -cfg2 $3 -o $@ $<

Is it possible?

dep.o: dep.src config1.cfg config2.cfg
    @echo the second preq is $(word 2,$^), the third is $(word 3,$^)
