You should be creating an office template file ...
In the meantime it is easy to bring over masters, layouts and views using the organizer.
Set both sides of your organizer to the layout book tab.
The right side will be the file you have open.
On the upper top left of the left side of the organizer click the arrow button and browse for the project that has the Master you want.
Drag and Drop it from left side to the right side of the Organizer.
If you do a search Djordje posted this when this feature was first available several iterations ago.
