How to exclude viewmodel properties from CA1811

Question

Using VS 2010/.Net 4.0, Code Analysis warning CA1811 (see below) is fired on all properties in a ViewModel even through they are used via XAML binding:

Warning CA1811 : Microsoft.Performance : 'BackupWindowViewModel.BackupCommand.get()' appears to have no upstream public or protected callers.

public ICommand BackupCommand { get { return _backupCommand; } }  <--- CA1811

<Button Content="Backup" Command="{Binding BackupCommand}" />

This is because Code Analysis (currently) does not parse XAML. My question is, is there a way to exclude all properties in all ViewModels (e.g. classes deriving from ViewModelBase) from CA1811? Having to suppress this warning on each individual property is a huge pain.
