Is it possible to have a custom item field with a formula that returns the unit price of a specific price level?

I've been able to accomplish the same result using a saved search using the following formula:
CASE {pricing.pricelevel} WHEN 'Special Clearance Price' THEN ABS({pricing.unitprice}) ELSE 0 END

The saved search method will not work for my task because I need two price levels (MSRP and Special Clearance Price) on a each result row. To accomplish this I group the items by their internal IDs. This means that all other fields in the results must also be calculations. Additional text fields are needed in the results and the formula text function has a limit of 1000 characters. Some of my text fields contain more than 1000 characters
