When you want to keep almost all properties and attributes of a style derived from another one, select the “parent” style in the Styles and Formatting panel (display it with F11
), then right-click and choose New...
from the popup menu.
An new style is created but notice it is “linked” to the parent one (Heading 2 in your case). Give it a new name like Heading 2 new.
Alter the properties which should be different from the parent style.
In your case, got to Text Flow
tab and check Insert (in Breaks part) Type Page Position Before (these two last are default).
Click OK
. You’re done.
If numbering is restarted from 1, go to Outline & Numbering
tab in style definition dialog and uncheck Restart at this paragraph box.
