Unable to use security editor to enlist new stocks for Dhaka Stock Exchange

[Dr. Md. Aminul Islam Khan]

I am trying to enlist new stock in the New security dialogue, but I do not find any DSE (Dhaka Stock Exchange of Bangladesh) in the Type box (The box where I have to select the Stock exchange). There are only AMEX, EUREX, FUND, NASDAQ and NYSE choices in Type box, and it is not allowing me to add the DSE stock exchange. How do I add DSE type in the Type box?

Can any one help me? Thanking in anticipation.
