Buy Sell orders

I want to BUY a Future Stock at a specific price before the market opens.
Can I place SLM in Zerodha before the market opens (I mean anytime)? It is just a pending order that will only be triggered when the market opens. So is it possible?

Also, if not, is there a script that can be written to "create a COVER BUY ORDER (market order) as soon as the market touches the BUY level I want? Then I can decide manually to close the Cover Order by moving the stoploss.

Please confirm if possible in PI and/or Kites?

Thanks.
