Using the subdue functionality with “dead man’s switches”?

We have some hosts that are posting keepalive messages in some remote sensu client as described in the dead man’s switch section in the documentation:

When the TTL expires and the host hasn’t posted a message we get alerts. We want to be able to silence these checks for some certain hours during the day, i.e. even if a host doesn’t post new messages and the TTL expires, no notification should be sent.

I tried to achieve that with the subdue functionality, but it seems that as long as the TTL expires an alert is sent and the subdue configuration is ignored.

Is it possible to use the subdue functionality to silence checks that are executed in a “dead man’s switch” mode?
