No sure what was the approach that you are mentioning.
There is a way to change global defaults for newly created interfaces - it's in Configuration -> Server configuration, parameter Objects.Interfaces.DefaultExpectedState
The other approach is to use scripting - either in configuration poll hook script (that script would go through interfaces of one node and change expected state) or a script that is meant to be executed only once and will go through all nodes and all interfaces of these. I can provide an example
