How to add view to a PRISM TabControl region WITHOUT making it selected?

We have a WPF application using PRISM, with a region of type TabControl.

    <TabControl prism:RegionManager.RegionName="{x:Static inf:RegionNames.ContentRegion}">
        <TabControl.ItemContainerStyle>
            <Style TargetType="{x:Type TabItem}">
                <Setter Property="Header" Value="{Binding TabName}" />
            </Style>
        </TabControl.ItemContainerStyle>
    </TabControl>

And we are registering views with

_regionManager.RegisterViewWithRegion(RegionNames.ContentRegion, typeof(ContentView));

Problem is, this way the registered tab automatically gets selected. Is there a way to add a view as tab but NOT select it??
