I´ve seen that there is a way to mark packages as deprecated on nuget.org (https://devblogs.microsoft.com/nuget/deprecating-packages-on-nuget-org/).

Unfortunally I don't push my packages to nuget.org but to an internal file repository. So my question is: Is there a way to mark a local package as deprecated (e.g. by editing the nuspec-definition or putting a file in my folder structure?
