Pulling individual groups into a dashboard

I have a dashboard that is connected to multiple boards; each board has a specific group where projects/pulses are moved for review.

I have the dashboard setup so that only those review groups pull into the dashboard - the remainder of the groups on those boards are not visible in my dashboard.

Recently, I went to add a new board/group into the dashboard, but I no longer see an option to limit the groups that pull through - All groups of the new board are pulling through. However, the boards that were already connected are still only showing the review groups.

Has this functionality moved, or is it no longer available?
