How do I modify the "Masked Input Widget" to allow the user to enter a negative dollar value?

In using the "Masked Input Widget", I would like to keep the figures entered to show as currency and include comma if the user enters figures that exceed 999.

The widgets contains the desired formatting controls but is lacking the ability to allow the form creator to decide if we wish the form user to enter both positive and negative numbers.
