Change default config for group sharing for new dashboards

[vmCalgary]

vrops 8.12.1 version

When I import a dashboard from {CODE} or other source, the default group is wrong. Where do I configure the default group for new dashboard imports? 

I know how to change the sharing for each dashboard, but I want the default group to be group B, not group A, when I import.

Not sure if I fully understand. But are you talking about the user who imports the dashboard? Else can you share a screenshot?
