I would like a way to count cards that are part of kanban style boards.

On the weekly agenda template there is a “to do”/”done” count (see below for screenshot). This is great but it’s position looks as though it impacts Monday only rather than the whole week. I would also like to use this functionality (count of cards etc) on my own templates. 

I have searched community post but cannot find a way to re-create this myself.

Please let me know how this can be re-created. Thank you.
