noalert for specific if statement in service check

[Britt Treece]

I have two set alert emails in the global section of my config

set alert address@hidden

set alert address@hidden

I would like usera to get all alerts and userb to only get some alerts.  Specifically I would like userb to only get alerts for filesystem space usage if it's over 95%. I tried the following configuration for the filesystem check but the noalert statement appears to function only for the check not for a specific if test

  check filesystem data with path /dev/sdb

    if space usage > 90% for 5 times within 15 cycles then alert

      noalert address@hidden

    if space usage > 95% then alert

Is there a correct way to configure this?  I am using monit 5.4.1.

Thanks,
