Order notification integration: how to customize the block on the order header?

Hello together,

I have activated the order notification integration for a certain order type.

Now I see that in the order header a block with notification data is available:

My questions are now:

1) is it possible to modify the layout of this block in the customizing?

2) on tab "Damage" you only see the fields for the damage and the cause - how to include also the object part and activity?

3) breakdown indicator: any change (user exit?) to have the breakdown indicator set active by default for a certain combination of order type and mainteannce activity type?

4) Malfunction end date/time: any way to have those filled automatically with date/time of the technical closure of the order?

Thanks in advance for your appreciated inputs!

Regards,

P.
