Not supported comments of schema.rb of rails

In schema file, I have comments for columns and tables, like

 create_table "pps_excel_column_customs", options: "ENGINE=InnoDB DEFAULT CHARSET=utf8", comment: "딜리버드 사입/배송 요청 엑셀 양식 커스텀", force: :cascade do |t|
    t.bigint "pps_user_id", null: false, comment: "딜리버드 사용자 id값"
    t.integer "excel_type", null: false, comment: "엑셀 타입(0: 사입, 1: 배송)"
    t.integer "initial_row_num", null: false, comment: "주문 정보 시작행"
    t.string "form_title", null: false, comment: "엑셀 양식 이름"
    t.text "column_def", null: false, comment: "컬럼 별 attribute 정보"
    t.datetime "deleted_at", precision: 6
    t.datetime "created_at", precision: 6, null: false
    t.datetime "updated_at", precision: 6, null: false
  end

but no comments in converted dbml file, like

Table "pps_excel_column_customs" {
  "id" varchar
  "pps_user_id" bigint
  "excel_type" integer
  "initial_row_num" integer
  "form_title" string
  "column_def" text
  "deleted_at" datetime
  "created_at" datetime
  "updated_at" datetime
}

Thanks for the suggestion, @yang94lol.

We have noted your idea and will consider it in the future.

Cheers.
