Reopening #934 for further discussion

          Hi, I am facing the same issue and it would be nice to have an alias for nested relations, because I have to query very deeply nested relations sometimes.

I have a solution for this, what if we create a separate AllowedInclude::alias($name, $internalName), that will directly zip the two arguments. Instead of building separate path for every nested relation.

If this is okay with you, I can implement this :)

Hey @MrAlpha786, I'm happy to look into a better way to handle include aliases. A separate AllowedInclude method is probably the way to go at first. If the new approach works out better than the current relationship method, I'm also happy to swap both of them in a new major version. Just to be more consistent with the way people expect this feature to work. Interested to hear your thoughts!
