Using rmlint, move duplicates to separate drive, retaining directory structure

I've been using rmlint to move duplicates to a separate volume, employing the user-defined-command feature. However, I'd also like to retain the directory structure, but I don't see any way to do that. I've used this so far
Code:rmlint -c sh:cmd='mv $1 /Volumes/2p5-750-2/'$1 .suggestions much appreciated. Thanks.
