Track the number of contracts a subscriber is "autotrading" on my strategy

Is there a way to track the number of contracts per trade a subscriber is “autotrading” on my strategy

I believe their is no way to do it for an individual subscriber. I think they prevent this to prevent legal barriers being broken. As you may already know you can look and see the total for closed trades. Just take note that the fills that are shown are not necessarily per subscriber. Often if one subscriber may get various fills.
