HassOS docker options

I’m running HassOS on a raspberry pi and would really like to get the docker logs forwarded off to my syslog server. The easiest way to do this is to add something like the following to the docker options:

  "log-driver": "syslog",
  "log-opts": {
    "syslog-address": "udp://"

Short of building my own HassOS image (ick), is there a way to add anything to the docker option in HassOS?
