Provide Multiple Functions to a column in formhandler

[umang-gramener]

Is your feature request related to a problem? Please describe. Problem is the ease of access for using multiple functions in a formhandler column response. Right now we need to write a form handler query to get the same thing done

Describe the solution you'd like looking for a shorthand to do queries like count(distinct(column_name)) while using the formhandler for getting grouped data.

Describe alternatives you've considered Write the same query in queryfunction

Noted, @umang-gramener -- we'll explore COUNT(DISTINCT) to begin with, and expand as we progress. Thanks!
