Shortcut for theme styling in XAML / UWP - xaml

Question

Hopefully this isn't a stupid question but I've spent several hours looking for this answer with no results.
Basically, I want to be able to control the appearance of hovered and pressed buttons. I've included the code for one of my buttons below.
Here are my issues
I have other buttons in my UI that I want to be able to assign this same style to
I'd rather not copy/paste all this code because if I ever need to change the colors later, I'm screwed
The <style> tag doesn't work because it can't set hovered/pressed colors (if this is actually possible please let me know)
Overriding the theme (as has been suggested in others answers) doesn't work because only some of the buttons need to be styled this way, but overriding the theme changes all the buttons
<Button Margin="5" Click="Settings_Button">
<StackPanel Orientation="Horizontal">
<FontIcon Glyph="" Margin="0,0,10,0"/>
<TextBlock>Settings</TextBlock>
</StackPanel>
<Button.Resources>
<ResourceDictionary>
<ResourceDictionary.ThemeDictionaries>
<ResourceDictionary x:Key="Default">
<SolidColorBrush x:Key="ButtonForeground" Color="#FFFFFF"/>
<SolidColorBrush x:Key="ButtonBackground" Color="#212121"/>
<SolidColorBrush x:Key="ButtonForegroundPointerOver" Color="#FFFFFF"/>
<SolidColorBrush x:Key="ButtonBackgroundPointerOver" Color="#424242"/>
<SolidColorBrush x:Key="ButtonBorderBrushPointerOver" Color="#FFFFFF"/>
<SolidColorBrush x:Key="ButtonForegroundPressed" Color="#FFFFFF"/>
<SolidColorBrush x:Key="ButtonBackgroundPressed" Color="#070707"/>
</ResourceDictionary>
</ResourceDictionary.ThemeDictionaries>
</ResourceDictionary>
</Button.Resources>
</Button>
Thanks!

Basically, I want to be able to control the appearance of hovered and pressed buttons. I've included the code for one of my buttons below.
The better way is custom Button and set internally ButtonBackgroundPointerOver in the style.
Steps:
Make Complete Control that inherit Button.
public sealed class CustomButton : Button
{
public CustomButton()
{
this.DefaultStyleKey = typeof(CustomButton);
}
}
Edit the default the and add the ThemeDictionaries
