Need a "Next Available Container" API call

[#1]

Hi is there a "next_available_container" call similar to "next_available_network" or "next_available_ip".

I need this function in particular instead of Network, it needs to be Container.

Alternatively is there anyway of just retreiving the "next_available_network" without creating it? i.e using the GET method instead of POST. I could then use the retrieved CIDR to create a Container.

Thanks

I need this function too. Since as Infoblox Terraform provider does not have "next_available_container" I want to know if there is an API call for this.
