With the Enhance my board and backlog feature, we can now see the subtasks of issues on the Backlog of company-managed scrum projects.

Users can go to Backlog > View settings > Subtasks and select Expand all to view the subtasks.
But, they would need to do this manually on every CMP Scrum board in order to view the subtasks.

Suggestion:

Have the option to enable/disable viewing of subtasks on all company-managed scrum projects, such that users do not have to go to each single scrum board to enable/disable this feature.
