"Insert Disk" confirmation, Tape Drive

Hi,

I have a little problem with Acronis Backup & Recory 10. It is actually stored on a NAS, but also now the owners want to have a backup to tape. The tape drive is a Tandberg TS400 (200/400 with Bands).
Whenever he wants to save on tape, I just confirm that a disk is inserted. Otherwise, the backup will not start.
Because the backup is running at 22h. I can't confirm that message. Is there a solution that automatically starts the backup?

... and sorry for my english :o)
