How to get subset of columns from List of Dictionary

Question

Our store procedure on DB returns me list of Dictionary and it has over 50 columns. Before I return this to user in gridfield how to get subset of columns from that List of Dictionary? In other words i need new list of Dictionary with just a few columns. for example extract columns {"Amount", "id"). 
 I'm using version 20.1
