Tape Libray and tap usage

We have a Dell ML6020 with three IBM drives and an 82 slot library.  DPM uses 
one tape per group per day (we perform daily tape backups to tape) even if 
the backup is only 25% of the available tape storage.

Is there a way to make a tape libary use a tape for multiple backups until 
it has become full.  This can be for the same group over mulitple jobs (days) 
or several groups it doesn't matter either way.  I just want to take 
advantage of the available 400 GBs on the tape.

Thanks for your feedback.
Right now there is no way to achive this.
DPM team is considering this improvement for the SP1.

Thanks,
