Allow Event Frame Variable values to be used in a Notification Rule email

I have a scenario where we are sending alerts on how well a fermentation batch has performed. I need look at attribute values at a specified timestamp and compare the other values at that same time. Easy enough right? The problem is I cannot send those values in the email alert because the attribute/pinpoint may have already received some new values or some may have been entered out of order causing the values in the email alert to not match up with what actually happened for that particular batch. I can get the email alert to go out no problem based on my critiera but I can't put extra information in there because the values aren't correct especially in the event of out of order events which happens frequently with manual lab data entry.
