Option to have view number counter display all conversations (instead of just open conversations)

It would be amazing if there were a way to (when we're setting up a new Public Tag/Custom View/View) to have the number counter show all conversations with that tag, not just open ones.

We are starting to heavily use public tags/custom views a way to pass tasks around our global coverage, and currently we need to do some workarounds to make sure that conversations stay open so they number appears. Having a way to set a Public Tag/Custom View/View to "everything with this tag" would make thing incredibly easier.
