Hey there, I’ve been recently creating global blocks using dynamic content so that I can manage a single block over several layouts. The only drawback to this approach is that when I am in the global block editor, I cannot view the content I’m editing while I’m editing it, because all of my dynamic fields aren’t in the loop while using the global block editor. Instead, I have to create the block on a layout page, save it as a template, and import the template into the global block editor. Likewise, making element css changes within the block is cumbersome as well, since I cannot see the dynamic fields while using the editor.
So, that being said, I thought it would be very nice to be able to select a preview product, post, archive, or page, etc. within the block editor like you can in a layout editor, so that I can view the content of the dynamic fields while editing a global block. I hope that makes sense.
