Displaying a document in Excel planning layout

Hi,

I have attached a document in ALV Planning layout. Then I changed the format of the layout to Excel. In ALV I could see the cell as highlighted when a document is attached to it but in excel I can´t see the highlighted cell or icon to mention that this cell is having some document attached with it.

Can anyone tell what setting are required to display the icon or highlight the cell in the excel when a document is attached to it.

thanks
