If the ball is hit toward 3B foul line, PU says "I've got the ball, Jim!" Jim can line up the catch for R2's tag, but doesn't make the call. PU should already be down the line, so he's there for R2's tag-up into 3B.

It sounds good on paper, but the entire mechanic falls apart if your partner's name isn't "Jim".
