How to handle symbol change in Fibotrader eg INFY from INFOSYSTCH

Hi,
I am using Fibotrader and I import the daily EOD data from the NSE website into it. Now the problem is that infosys has changed it's symbol from INFOSYSTCH to INFY. As a result in Fibotrader I have 2 symbols for Infosys which is messing up my charts. How do I tell Fibotrader that INFOSYSTCH and INFY are the same company?

Thanks!
