Option for different strike price selection for call and put

In split view when I select say 26000 call then it automatically applies to put option also. There should be option for permanently setting preffred strike price for both seperately. I like to trade option in range of 40-50 rs, they need not be of same strike price. Sahi scalper mode is better in this, they also have put + call and nifty + call/put chart option which is game changer, you can refer it and impliment here also.
