[monit] 'flag' files

I have a daemon that sometimes needs to be down once in a while.

In my pre-monit days, my custom rc scripts would leave a 'flag' file
in /var/tmp for the accepted down time (and remove it when restarting
the server) and my custom watchdog script had logic like this:

if server is down
   if flag file exists
       do nothing (since flag file exists, and we down for an ok reason)
       attempt to bring up server (since we are down Unexpectedly)

I'm sure that is simple in monit, but after reading all the examples
on the man page and the FAQ, I cannot figure out how to do this.
Probably I'm just dense.  Do people just modify the monit
configuration file 'live' instead of using flag files?  The 'ok'
downtime is on the order of 15 minutes or so, but doesn't happen on a
regular schedule.

I tried to search in the mailing list archives, but I haven't found a
working search string.

Just using the pid file missing doesn't work, since it goes away for
both scheduled and non-scheduled daemon outages.

If you flame, please also provide a link to the solution.
