You could do this through an app that you'd have to code your self - using CR RDC APIs, CR SDK for VS .NET or CR SDK for Java.
But, 1st you'd need to ensure that you are using CR XI R2 (11.5) - at least, preferably CR 2008 (12.x) or even higher. And then the app would have to use Report Creatin APIs. With the RDC, this would involve referencing the craxddrt.dll in the app. With .NET or Java, you'd have to use the InProc RAS SDK.
No other way.
