When evidence which is admissible as to one party or for one purpose but not admissible as to another party or for another purpose is admitted, the court, upon request, shall restrict the evidence to its proper scope and instruct the jury accordingly. In cases tried to a jury, evidence inadmissible as to one party shall not be admitted as to other parties until the court has made all reasonable efforts to effectively delete all references to the parties as to whom it is inadmissible.
