The (normal) environment is one backupset, one tape.

Possible workaround:
Create a second TSM server (or a second instance on the existing TSM
server) that uses a separate library (or possible a logical library
within your existing physical library). 
Set up server-to-server communication, and use a server-based device
class to send backupsets to a virtual volume on the source server. 
The target server will 'stack' multiple backupsets on a single physical
tape.
