Hide Subitems from Cards View Widget

Hi! Is there a way to hide sub-item cards from the cards view widget on dashboards? I only utilize the sub-items to link supplemental information back to the main item/pulse. So, in the cards view widget at the moment it’s creating unnecessary duplicate card views [One for the main item, and then a separate card view for the sub-item].

Thanks!

Can someone pls respond here? +1 as there’s no need for sub-items in cards view. Thx!
