Can we place good till cancel orders in Zerodha System for managing portfolio stock downside risk mechanically?

Suppose I have 5 Stocks in my Portfolio with Qty & Price as Follows

StockA 500 @ 300

StockB 1000 @ 450

StockC 5000 @ 250

StockD 1000 @ 900

StockE 250 @ 700

Now if I want to place stoploss order good till cancel for all these five stocks and then modify it whenever I want.Is it possible.What about the margin consumption in this case.

Regards

good till cancel GTC is not available as of now.
