I wan't to replace my hardcoded urls in my angular services with something more dynamic and found the our article on Server variables & URLs

I've added a new eventhandler and implemented the Parsing method with the custom routes and to a dictionary item with the name of my package.

dictionary.Add("package_name", new Dictionary<string, object>
{
    {"Api", "url"}
});

When calling the Umbraco.Sys.ServerVariables["package_name"] the added variables show up.

I was hoping I could use umbRequestHelper.getApiUrl to retrieve the urls, in my angular code, but after looking in the source code I see the getApiUrl is hardcoded to only look in Umbraco.Sys.ServerVariables["umbracoUrls"].

So my question is, what is the correct way to have umbRequestHelper look for my custom routes in Umbraco.Sys.ServerVariables["package_name"]?

For now I've added my own service with a literal copy of getApiUrl that looks in the custom Umbraco.Sys.ServerVariables["package_name"], so my code works but it feels hacky.
