Is there any way Zoho can "read / detect" an already assigned ticket number in the subject header or body of the email?

Example: Ticket [## 19662 ##] **URGENT** Ocean Quote - Normagroup

Now, when someone who was in copy replies to this email or an RE: gets placed in the front of the email automatically via outlook, our system creates an entirely NEW ticket which is then prompting us to search our tickets for "similar tickets" to then merge them...

We're spending a TON of time merging and at for the rate of traffic we have, the merging of the tickets is becoming a job onto itself which was not the intention of switching over to the Support System...

I need a comprehensive solution to this ASAP.
