Ah, ok. So in the list of dashboards, you’d like to group them somehow?
I usually create a ‘navigation’ dashboard for my devices. I have that navigation dashboard set as my Start URL on my tablets and used the Add to Homescreen approach for my phone so the navigation dashboard loads directly.
You may have noticed in my screenshot that I named my favorite dashboard starting with a space and then a star emoji. The space as the first character sorts it to the top of the list and the star is just a quick visual so it’s easy to find.
