Question: Hidden execution group boundaries

The new default in Maple 2025 is to hide the Execution Group Boundaries in Worksheet mode.
In order to make them visible one has to use the menu

View > Show/Hide Contents > Execution Group Boundaries F9

or to press the F9 key.

The question: is there a method to have again visible boundaries by default? 

(Hiding the boundaries does not seem to be a good idea because an execution group can have (it is not clear why!) multiple prompts.)
