Does the nuget.config spec allow us to specify Symbol file (.pdb) locations?

I love how the nuget.config has packageSources and packageSourceMapping. That really simplifies people getting started with my projects without having to do custom setups in their GUI of choice.

But .. what about symbol file locations? Sure, Visual Studio (not sure about Rider, etc) auto checks nuget.org for symbols if the nuget package has snupkg's up on nuget.

But it all breaks down terribly if we are using private nuget repositories to store out nuget packages.
We now have to manually add in the Symbol Server to our GUI, like this:

So ... would be really awesome if we could have the ability to define where the symbol packages also exist . We already tell the program where our private nuget repo is. Why not where the private symbol server, is?
