I'm using OpenApi generator to generate http client for api tests. I'm using csharp-netcore generator. I want to pass a mapping for models to reuse api models. The problem is that I have lots of classes and when I provide a mapping for all classes using importMapping option I hit command line max length limitation. I need mapping because namespaces are different for all models and I can't put them all into a single namespace to match auto-generated client. Is there a way to pass this configuration from a config file to bypass command line length limitation?
