You'd be stuck with cut-in lines between the tails, use a pencil for that line.

Many makers cut that line in deliberately, even for routed dovetails.
Sme years ago one of those strange orange-skinned TV antiques chappies
said that "good dovetails were marked out with a knife" and so ever
since then this has been seen as a sign of "genuine" work.

I admit I leave the lines in place on drawer sides, but not on the
outside of a carcase.
