Is it possible to do [TimerTrigger("%my_config_value%")] and/or use INameResolver?

Before it was possible to get schedule from config or even register a custom INameResolver to resolve "%xxx%" in runtime.
With the worker I'm getting "Microsoft.Azure.WebJobs.Host: Error indexing method 'xxx'. Microsoft.Azure.WebJobs.Host: '%xxx%' does not resolve to a value." before Main() is even called.
Well, the only reason we use "%xxx%" in Timer triggers is because there is no way to specify trigger time zone. Which is a degradation since Azure Functions V1 which did support it. Yes, I know I can run whole app in whatever time zone I want but it is not a valid solution because the rest of our code expects to run in UTC (which is a best practice btw).
