Online shared Excel 365 workbooks appear to open to the last cell a user clicked. This is no good if we are trying to display information to a team.

Could you please give us the option to open sharepoint docs at sheet1!A1 as with the desktop Excel.
or failing that, allow us to specify cell sheet1!A1 in the sharepoint URL to that workbook
