It would be very useful to be able to display the number of items referenced by a collection Item.

For example, having a list of tags and being able to display the number of items with such a tag, or being able to display the number of products within different categories or subcategories. From what I've been able to tell, the only way is to use the Webflow API, which is admittedly above my head and pretty far from a native experience in WF.
