add custom column in search ad 360#916

hi, appreciated if can add custom columns in search ad 360 API: https://developers.google.com/search-ads/reporting/concepts/custom-columns

Thank you for your prompt attention to this matter.

To clarify our requirements, we need to extract the following data: campaign, ad group, engine (account type), cost, impressions, clicks, and custom conversion data. The custom conversion data should be broken down into individual columns, each labeled with the corresponding custom conversion name.

Hope it helps facilitate your work!
