Remove all downtime for a host via API

[Brickius]

Im trying to remove all downtime for a host + its services via the API

I can remove host ok:

/hosts/HOSTNAME/cmd/del_active_host_downtimes

But for services I cant figure out how to specify "all" i.e. I can do it one by one by pulling the list of services but its not a very efficent way of doing it

/services/HOSTNAME/*/cmd/del_active_service_downtimes"

I cant seem to get the filter here to recognise regex:

"message" : "cannot send command, affected backend list is empty. no object found by filter: host=HOSTNAME service=*"
or
"message" : "cannot send command, affected backend list is empty. no object found by filter: host=HOSTNAME service=.*"

I can do it with the system command:

/system/cmd/del_downtime_by_host_name" -d "hostname=HOSTNAME"

But I dont really want to give this user that level of power

Instead of pulling the list of services, i would pull the list of downtimes
