is there any tools in the Business Intelligence Studio which can be used as Rules Engine?

I want to create business Rules from BI Development Studio. This will be a replacement of creating Stored Procedure. Most of the Business Rules are in the form of Stored Procedures since the DB is based on SQL Server 2000, but, it's migrating to 2005 server, so, it would be ideal if something in the BI studio can do Business Rules.Moving to SQL Server Tools General forum.
