What you're asking can be solved by applying ReSharper's Code Annotations to your helpers! I recently recorded a webinar with JetBrains called ReSharper Secrets, where I talk in depth about Annotations, and actually show how to do the very thing you're asking! (around 32 minutes in)
Basically, you need to apply the [PathReference]
attribute on the string parameter of your helper methods that represents the path, and you're done! I wrote a blog post about how to do it, you can read it here.
