Customization Facebook OpenGraph Title I am using SEOmatic on Craft 2 and want to give the user the ability to customize the Title field of Facebook's OpenGraph Title. For example, instead of showing just the Title, add a "How To" before the title is displayed. 

vs. 

Is there a way to do this without using a custom field and have the "How To" only display only on when the article is shared on Facebook?
Referring to this page, you can try this:

{% set og = seomaticMeta.og %}
{% set og = og | merge({'title': 'How to: ' ~ seomaticMeta.og.title}) %}
{% set seomaticMeta = seomaticMeta | merge({'og': og}) %}
