Can default display unit be changed for a scout in multiple units?

Thanks! I had checked the My Memberships page, but didn’t drill down into the individual unit memberships where the toggle is hiding.
That seems to get us at least halfway there. The dashboard is still displaying the percentage for the next crew rank, but when I click on my son it does take me directly to the view related to the troop that is his primary unit. Should I dare to hope that when things sync the dashboard might follow suit? Either way, it’s a big improvement.
The thing that seemed really odd about this is that in myscouting the troop is his primary unit. I assume that’s the official registration database you were referring to, so increasing integration should be keeping this from happening!
