No. Specifying the tape to use is absolutely against Baculas design. 
Use tar if you want that...

You specify the pool.

Yes.

Create two pools, one for full backups, one for incrementals.

Set the retention times suitably high, or even to "forever". Don't 
automatically recycle.

Add one tape to the full pool and one to the incremental pool.

Run a full backup, specifying the full pool as the target.

Store the tape safely (and be aware that many people - including me - 
believe that it's wise to have more than one full backup lying around...).

Schedule incrementals to happen whenever you want them.

At the end of the year, run two migration jobs to 1. move all data 
from the incremental tape to a temporary pool on the disk, and 2. move 
from that temporary pool to the full tape pool.

Disable or set to "Used" the full tape, so Bacula will not 
automatically use it again.

Recycle your incremental tape, buy a new tape and add it to the full 
tape pool, run a full backup again and let Bacula do it's incrementals 
as scheduled.
