Filter to match 2 data fields

Hi, Other than in a business process, is it possible to create a filter on a list page, which allows me to compare two data fields from the record.

For example, if I want to compare which products have the same Vendor Code with my internal code (not that anyone entered the data incorrectly you understand!) or where opportunities have a budget amount the same as the final sale price, I need to be able to filter based on Field x = Field Y.

thanks
