Move Interaction.Behaviors to Style, Template or something else - xaml

Question

I have many XAML TextBlock which looks like this:
<TextBlock Text="{Binding InspectionCount}" Style="{StaticResource FilterText}">
<i:Interaction.Behaviors>
<core:EventTriggerBehavior EventName="Tapped">
<core:InvokeCommandAction Command="{Binding SetModeToAll}" />
</core:EventTriggerBehavior>
</i:Interaction.Behaviors>
</TextBlock>
I want to reduce amount of XAML code and write something like this:
<MyTextBlock Text="{Binding InspectionCount}"
Style="{StaticResource FilterText}"
Command="{Binding SetModeToAll}" />
I know only one way to do such things - create the new class (which is inherited from TextBlock), add AttachedProperty (Command) to new class, and create a Style for a new class.
But looks like I cannot inherit my class from TextBlock:
public sealed class FilterTextBlock : TextBlock
Cannot inherit from sealed class TextBlock
Why I can not do it? May be there is other way to do what I wish ?

I have discovered that the following WORKS. and solves the question from many places, I will start answering, Try the following!
<Page
x:Class="Example1.ListBoxTest"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:Example1"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:i="using:Microsoft.Xaml.Interactivity"
xmlns:core="using:Microsoft.Xaml.Interactions.Core"
mc:Ignorable="d">
<Page.Resources>
<i:BehaviorCollection x:Key="behaviors">
<core:EventTriggerBehavior EventName="Tapped">
<core:InvokeCommandAction Command="{Binding SetModeToAll}" />
</core:EventTriggerBehavior>
</i:BehaviorCollection>
<Style TargetType="TextBlock" x:Key="textblockstyle">
<Setter Property="i:Interaction.Behaviors" Value="{StaticResource behaviors}">
</Setter>
</Style>
</Page.Resources>
<Grid x:Name="LayoutRoot" Background="Transparent">
<TextBlock Text="Testing" Foreground="Red" FontSize="20" Style="{StaticResource textblockstyle}">
</TextBlock >
</Grid>
It is curious, if I set the behaviors inside the propery i:Interaction.Behaviors does not work but in this way the Command is called!!
Please tell me it works you too!

Just use:
<Setter Property="i:Interaction.Behaviors">
<Setter.Value>
<i:BehaviorCollection>
<MyCustomBehavior />
</i:BehaviorCollection>
</Setter.Value>
</Setter>
inside the <Style TargetType="TextBlock"> tag.
Don't forget to include xmlns:i="using:Microsoft.Xaml.Interactivity" at the top of the page.
