As far as I can remember, there's no exact duplicate of that in Storytelling (but others may correct me.) However, you can achieve something similar, but it's a dangerous thing to try and pull off, as you have to practically engage the opponent, becoming a potential target for them as well. (Right, coming to think of it, the same holds true of Pathfinder as well, where the opponent can also switch to attacking you.)
It all comes down to the workings of the Defense trait. Remember, each subsequent attack against a character in the same round reduces said character's Defense by one (nWoD, p90). All you and your co-attacker have to do is agree on you attacking first, and your co-attacker delaying their attack until you've completed yours. This way your opponent will have a smaller Defense against your co-attacker's attack.
Sure, your opponent may decide to use their Defense only against your co-attacker (nWoD, p156), but in this case you'd have a much greater chance to score a hit, since their Defense would not be applied against your weaker attack, as delaying the application of Defense for a specific attack denies all Defense for any attacks coming before the specified attack.
Again, this is dangerous, as you have to practically enter combat, and may become the opponent's primary target - but the same holds true of the Pathfinder option as well, imo.
