Oracle Stored Procedure for RDLC Dataset

Is it possible to use an Oracle Stored Procedure for an RDLC report. There are posts I've read that deal with RDL reports that use the data tab and command type of "Stored Procedure", but I don't have that installed. I just create a new dataset that the report uses. I can do reports just fine with SQL statements, but I want to be able to call a stored procedure...

Thanks

Another post that seeks to answer this question is at

"Hi, i have used rdlc with the informix database. What is did was add a empty
dataset to the rdlc and i have a business layer (a vb class) which has a
function which returns a dataset. When you add a report to the page add an
objectdatasource and specify the type as the vb class and the select method
as the funtion. This works for me. "

Is this the only way to accomplish this? Does someone have the definitive answer of "No, an

Oracle Stored Procedure cannot be called by a setting in the dataset wizard for a client-side (RDLC) report."

Also, here is a post that deals with just the RDL report:
