Does Convox have plan to support at a ECS task definition level the `--dnsServers` parameter?

[https://docs.aws.amazon.com/AmazonECS/latest/developerguide/task\_definition\_parameters.html](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/task_definition_parameters.html)

I can’t quite see it supported in either gen1 or gen2 manifests at the source code level, hence asking.

If no, does it mean I cannot make my Convox apps use a custom DNS server (such as Consul) as service discovery? Is there any way to workaround it?

TIA.
