When I leave my dashboard and come back the record selector defaults back to the alphabetical first values in each selector.
When I use the dashboard it is essentially becoming a "work environment" and when I "leave" my desk I expect to come back to it and pick up where I left off rather than navigate back to it.
If possible, have the record selectors "remember" where you left off when you return to a dashboard.
Totally acceptable that if I've been logged out I need to navigate back, I'm mainly wanting it for when it's still the same session.
