Forcing full backups on a regular basis

Hi folks,

I'm using amanda to back up three servers using tpchanger "chg-disk".
Everything is working fine, however due to the fact that I don't have a real tape changer I'd like to be able to take a given snapshot of all systems from time to time and burn it to DVD. I've already configured the virtual tapes to be somewhat smaller than a DVD.
From what I understand "dumpcycle" only specifies that a full dump must happen (at least) every 7 days but otherwise it attempts to distribute those full dumps from various filesystems. Is there a way of enforcing this automatically so that there is a predictable schedule when a dump will contain a full backup of everything (i.e.: every Thursday night)? I realize I could probably run two backup schedules (one daily, one weekly) and turn incremental off on one of them completely, but that just seems clunky to me unless there's a way of utilizing the same tapes on two schedules?!
Alternately I guess I could build a little script that would allow me to build a full image on demand from the incremental if I understand amanda properly. That would probably suit my purposes as well. 

Any help would be appreciated!

cheers,
Gabe
