Need 'ticket' numbers in Contact Form 7

Hey,

My issue is that every email coming in is grouped together because they are the same ‘sender’ and same ‘subject’. I would like some way to have every email have a different subject. I have looked around but so far was only able to find a way that required an outdated plugin. I am not set on CF7 so if there is something else that does what I am looking for I am willing to consider moving. You can view the current form at jrummyapps.com/support to see what we are using it for.

Thanks in advance
