We have created a component that requires a different URL in the spec file library array depending on being run in our development environment or our production environment. Is there a way of having a dynamic URL specified?

```auto
{
	"name": "cesoftcomponents-api-example",
	"displayName": "api-example",
	"version": 1,
	"definition": "cesoftcomponents/api-example/api-example.js",
	"libraries": [
		{
            "name": "api-check",
            "version": "1",
            "mimetype": "text/javascript",
            "url": "https://test.api.io/js/api-check". <-- Needs to remove the test when run in Production
        },

```
