Add 'Select All' Feature in Custom Report

In my organization we heavily use Vizlib Custom Report v5.13.4 as a method to extract local data sets for program managers and basic business analysts. We have built standard templates in Custom Report. However, if an analyst or program manager desires to Select All columns in the Vizlib Custom Report they have to manually click the additional available fields, one by one.  Let's say a Custom Report has 200 available fields and the standard template is 40 fields.  The analyst or PM will have to manually click 160 fields, one by one.  I am politely requesting you please add a 'Select All' feature to Customer Report so it can add/ populate all fields in a single task.  Thank you.
