So, a separate bank for those monthly images?

The key here is that dirvish _always_ reads the master.conf first,
even if you specify --config.
You could move the bank specifications to a daily config file, and
always specify the daily config file via --config, and using the monthly
config file when making the monthly image.
Personally I would instead create a script to copy the latest daily
image to the monthly bank _after_ creating the daily image. That way the
client isn't being accessed twice for the same data. Of course if you're
backing up the local system, that doesn't matter much; if you're going
over the network things may be different.
Something like:
----------------snip-------------------
#!/bin/sh
set -e
MONTHLY=/banks/monthly
DAILY=/banks/daily
IMAGES='foo bar'
for i in $IMAGES; do
cd $DAILY/$i
newest=`ls -t | head -n 1`
if [ -d $newest ]; then
previous=`ls -t $MONTHLY/$i | head -n 1`
if [ -d $MONTHLY/$i/$previous ]; then
rsync -aH --link-dest=$MONTHLY/$i/$previous/ $newest $MONTHLY/$i/
fi
fi
fi
----------------snip-------------------
Totally untested :-)
