Perch related in blocks
Can perch:related be put in a template and used as a block so editors can add related collections. I think the template might need scope-parent=true.
Use case is adding related collections of articles, centers, or people. Plus it could be good way to interrupt the flow of a users reading experience.
I use perch:related in master page template as an aside which works great. But wondered if it might work with blocks.
