Can Crystal Reports use an existing DB connection?

Hello,

I have C# app (win forms) that connects to Sybase ASE (15.5) database using ADO.NET.  I have Crystal Reports (version 14.1.1.1036)  used by that application that use use stored procedures on that same server.  The reports now create their own connection; the app provides login credentials via SetDatabaseLogon().  Is it possible that the reports use the C# app's DbConnection to access the database?

Thanks,

John
