Not AFAIK.  Normally when I have something to do like that I use 
'tethereal' and a simple (in my case UNIX) shell loop, something like:

for f in *.cap; do
    echo "Looking in $f"
    tethereal -r $f -R "my display filter"
done

At least then you can find which of the files has what you're looking 
for (then maybe you can do a deeper analysis with Ethereal).
