Is there any facility to save orders

Is there anyway I save my order now with SL n target and execute at a later time during a trading day?

You can check out GTT Orders for this, it also comes with OCO (One Cancels Other) order which you can use to place Stoploss and Target. GTT will remain valid for period of one year from date of creation or until it is triggered. You can read this post to learn more:
