Overnight Funds - Done Automatically Daily

[Gaurav_Mehta]

Hi, I am new to zerodha and i read the following 2 articles here :

NSE's overnight investment facility: Will it be useful to you?

and

Overnight liquid funds investments - Are there ANY costs involved?

Hey recently Zerodha did quarterly settlements. As I had opted for buying overnight investments in liquid funds, Zerodha bought BoB fund for me. @nithin Are there really no costs involved in this transactions? I actually found that I gained ₹5 instead!!!

My question is this:
In the above example on tradingqna we are given the facility to opt for overnight funds on a quarterly basis(for settlement) only. Is there any facility where we can do the same on a daily basis to the amount in our account that is unutilised. eg-- Can we buy an overnight fund using say coin after 4 pm and sell it again after 8 am the next day. Or is there some sort of automatic facility for the same.

Not possible to automate this.

But is it possible to do this manually say after trading hours and then sell again the next day before trading hours and if yes how ?
