Putting an ItemContainerStyle on a Grid - winrt-xaml

Question

Obviously ItemContainerStyle doesn't exist in a Grid, which is the problem.
My program has a ListView that displays a bunch of projects. I want to add a button to each project that gives more info, and that much I can do easily. The problem I'm encountering is the border that appears on each project, which is toggled on/off by clicking the project to show the user which are currently selected. I don't want this border to encircle my button; I want the button placed to the right of the bit with the border.
I can't put the button on a separate list or I'll get two different scroll-able lists, so it must stay within the ListView, but any border on the ListView will encircle everything in the ListView. My solution was to make a StackPanel with two Grids inside the ListView, where the first Grid has all of my old stuff and the toggle-able border and the second grid only has my button. So now I just need to move that border onto the Grid... but how?
XAML code:
<!-- Other code up above... -->
<ListView x:Name="lstAvailableProjects"
Grid.Row="1"
ItemsSource="{Binding ProjectList, Mode=TwoWay}"
Height="Auto"
Width="Auto"
SelectionMode="Multiple"
IsRightTapEnabled="True"
IsDoubleTapEnabled="False"
IsSwipeEnabled="False"
SelectionChanged="lstAvailableProjects_SelectionChanged"
Background="Transparent"
VerticalAlignment="Top"
ItemContainerStyle="{StaticResource ActiveProjectListViewStyle}"
BorderThickness="30,0,0,0">
<ListView.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<Grid HorizontalAlignment="Stretch" Width="250" Background="{Binding Converter={StaticResource projectStateColorConverter}}">
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<TextBlock Text="{Binding ProjectName}"
Foreground="Black"
Margin="10 5 0 0"
FontSize="17"
VerticalAlignment="Center"
Grid.Row="0"
HorizontalAlignment="Stretch"/>
<TextBlock Text="{Binding AssignmentRole}"
Visibility="{Binding ProjectAssignmentRole, Mode=OneWay, Converter={StaticResource visibilityConverter}}"
Foreground="Black"
Margin="10 3 0 5"
FontSize="14"
Grid.Row="1"
HorizontalAlignment="Stretch"/>
<TextBlock Text="{Binding StatusText}"
Foreground="Red"
Margin="10 3 0 5"
Grid.Row="2"
FontSize="14"/>
</Grid>
<Grid>
<Button>
<Button.Template>
<ControlTemplate>
<Image Source="../Assets/setting_icon.png" Height="40" />
</ControlTemplate>
</Button.Template>
</Button>
</Grid>
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>

Since the grid items are wrapped You cannot make changes in xaml to achieve it other than overriding the preparecontainerforitemoverride.
A little tricky hack would be to apply transform to the button.
<Button.RenderTransform>
<CompositeTransform TranslateX="100" TranslateY="100"/>
<Button.RenderTransform>
