select all items within a whole file including all flows

Hello,

ctrl/cmd + a selects all item within an activated flow.
Is there a way to select all items in all flows in a file?

Currently, I would like to reset all frame breaks and system breaks simply.
However, I need it when changing specific properties of items across whole flows.

I need to select all across all flows as well. It would also be useful to be able to select a staff or group across all flows.

We don’t have any plans for this at the moment, but I wouldn’t absolutely rule it out for the future.
