Export Handoff documents in different file formats

Please add document export functionality for the following file formats: 1) Google Docs (.gdoc), 2) Google Sheets (.gsheet), 3) Microsoft Word (.docx), 4) Microsoft Excel (.xlsx). Currently documents can only be exported as PDF, but contractors need to share and edit documents in these common formats. This is particularly useful for rate reference documents and field schedules that contain large tables, which often don't render well in PDF format.
