How to modify bracket orders which are executed in multiple suborders

Hello,
Could somebody please help me with this query, I bought 100 shares of xyz stock in bracket order, now it got executed in 19 different orders, I had set a target of 10 rs , now I want to change it to 6, how do i modify all the 19 orders target to 6 in one go ?

Doing it individually will take ages and might miss on the price while doing it. Any suggestions?
