Can one xxdiff two directories and only include certain files?

[Matt Thompson]

As the subject says, I was wondering if one can use xxdiff to compare two directories but only compare matching files? Say I want to xxdiff all the .rc files in dir1/ and dir2/?

My guess is probably not (since GNU diff doesn't seem to be able to do this), but I thought I'd ask.
