Mobile view dashboard only tiles

When you are creating a dashboard, it is okay to have a running chart in web dash, but you might want to show just an accumulated number in mobile dash,AND I dont want to show that number in web dash.
The underlying idea is to have an option to have same "unpinned tiles" option on web dashboard and if one is feeling too lucky, sometihing similar on main report as well.
This main report unpinned item will be helpful, as in main report I would have various tabs, but in dashboard I wont, so I would I like to have some special tiles, not wanted in report, that I will put at start of each section. Text Options is there but that isnt too cool.
