WPF: Manage margin for all controls in a ContentPresenter

Is it possible to define the "presenting behavior" of a ContentPresenter so that it applies padding to its content?

Now I have a ContentPresenter and define the Margin on all UserControls that can be part of this ContentPresenter.

The downside of this, is that it calls for repeating definitions of Margins, and the UserControls are kind of dedicated to "fit" in the ContentPresenter.

E.g. XAML that contains the content presenter:

    <ContentPresenter 
        x:Name="SettingsContentPanel" 
        Grid.Row="0" 
        Grid.Column="2" 
        Grid.ColumnSpan="2" 
        Content="{Binding ElementName=SettingsGroupSelector, Path=SelectedItem.Tag}" />

And the user controls are defined as follows:

    <UserControl 
        <!-- left out irrelevant definitions -->
        Margin="5,5,5,5">
