GrapeJS Email Builder - Dynamic Content (Owner Field Missing)

My Mautic version is: 4.4.6

It’s good to see the return of the Dynamic Content Block in version 4.4.6.

However, does anyone know why you cannot build dynamic content based on contact owner from the block criteria?

I think this would be really beneficial for occasions when you want to include more than just the basic contact owner {signature} token.
