Rails migration generation with options or defaults

Rails
1

In Rails we have command to add migration that specifies the table name
column name. For example :

$ rails generate migration AddPartNumberToProducts part_number:string

will generate

class AddPartNumberToProducts < ActiveRecord::Migration
def change
add_column :products, :part_number, :string
endend

I know we can add the options on migration file, below migration will
add
part_number column after description column on products table.

class AddPartNumberToProducts < ActiveRecord::Migration
def change
add_column :products, :part_number, :string, :after => :descritpion
endend

Problem: How to specify the options (example :after => :descritpion) on
command line so that it will add directly on migration file.

FYI : I’ve asked the same question on stackoverflow Link

Allowing you to specify the columns on the command line generator is a
convenience feature. It was never intended to provide the full range of
options that can be specified in the actual migration.

There is a limited set of additional options you can specify on the
command line as detailed in section 2.3 of the following guide:
