Feel free to post your question in the HM Support thread and I will be glad to answer it for you in terms of how HM2 deals with that situation but I am not supposed to answer outside of our thread and I will not answer any PT4 specific questions. You will need to post your question in their thread also if you want an answer as to how they deal with that situation.
