Google Sheets Integration: Can I customize report?

I am using the google sheets integration and wondered if I can add rows/columns to customize reports? Will the report save my new additions? Also, can I remove rows or columns that are imported into the document through the integration that I do not need to see in my report? 

You can customize the spreadsheet, but not the fields on the form. Once you have integrated the form with spreadsheet, you cannot edit the fields in Jotform because this will break the integration. However, adding some notes, extra columns in the spreadsheet will not break the integration as long as the original fields that are integrated is not removed / modified.
