Accounting Format

Hello,
One of our requirements is to use accounting format for money. Samples can be found in Excel, just select "Accounting" from predefined format strings. With this format "$" is aligned to the left of the cell and amount itself to the right side.
Unfortunately, I was not able to find "normal" solutions for this.
Not "normal" solutions that I can imagine now.
1) Format string with hardcoded spaces. Actually this will not work with Excel export;
2) Add fake column before cell and add "$" here. Same issue, this will work with Excel export.
Is there any way to do this without hacks?
