FIX classid? ...and TIPS for FIREQOS_MIN_RATE_DIVISOR

Happy 2015!

I'm testing FireQOS... great tool... very very thanks Costa!
Before it I was using "htb" (writing the rules manually or with other tools)

I've a question....

Is possible to "fix" classid?

It is really helpful to identify the class or building charts (with
RRD for example), without losing the "index" in case of changes
(add/delete before/after).

PS: This is useful for distributing all the guaranteed minimum
bandwidth to all classes (if not specified manually):

FIREQOS_MIN_RATE_DIVISOR=`cat /etc/firehol/fireqos.conf | grep class |
grep -v FIREQOS_MIN_RATE_DIVISOR | sort | uniq | wc -l`
