Accounting Format, Rounded to the Nearest 1000

Hi,

I have a budget spreadsheet where I would like to display values rounded to the nearest 1000, without changing the actaul value. I want to keep the accounting format with the $ sign and ( ) for negative numbers. An example $8,965 I want to display as $9,000. If it's negative $(8,965) then as $(9000). The value needs to stay as the 8965.

Thanks for the help!
