Oddly enough, yes ;)
It's in the comments in the example amanda.conf.

Will that work ?
If I specify a chunksize of 1G, and dump a 9G backup, will it stick 3
chunks on each of the 3 hilding disks ?
That would be really impressive ...

Line 82 and on in example/amanda.conf in the source tree
# Specify holding disks. These are used as a temporary staging area for
# dumps before they are written to tape and are recommended for most sites.
# The advantages include: tape drive is more likely to operate in streaming
# mode (which reduces tape and drive wear, reduces total dump time); multiple
# dumps can be done in parallel (which can dramatically reduce total dump time.
# The main disadvantage is that dumps on the holding disk need to be flushed
# (with amflush) to tape after an operating system crash or a tape failure.
# If no holding disks are specified then all dumps will be written directly
# to tape. If a dump is too big to fit on the holding disk than it will be
# written directly to tape. If more than one holding disk is specified then
# they will all be used round-robin.
