Tools to add in Export - Manage in Workbook

Content (required):

Hello all,

We have a new requirement to add some tools in the spreadsheet and I would like to ask if anyone knows if its possible to achieve this.

1. Add a filter to the Export - Manage in Workbook: I found out that it is possible to add the filter only after downloading the spreadsheet and not retrieve the filtered worksheet. Can someone confirm this?
2. Does anyone know if it is possible to view only the visible columns from the worksheet in the spreadsheet and not the initially hidden columns from the worksheet?
3. Is it possible to view the budget breakdown and allocation in the spreadsheet?
