I think those settings are inherited from the platforms you use. You can use script like this to change all outline boxes to be horizontally closing (some platforms might use special outline boxes so those orientation won't be changed...).
(Current Journal() << XPath("//OutlineBox")) << Outline Close Orientation("Horizontal")
You could also use similar idea on your reports before you move them to journal using Current Report() instead.
There seems to some preference for this, but no idea for what really
