This is an old thing, but i find it very handy, so why not share.
Right click on the layout and choose from template... Know you find the drawing you would like to import the layout from. If you need more than one you simple choose those you need.
I´ll give you an example.
If i have 3 levels, i start with the level 1, and here i insert a Title block, drawing frame, viewports, notes etc. etc.
When i create level 2 and 3, i only have to chance 2 or 3 things in the Title block, ex amble from ground floor to 1 floor and so on. This is really a time saver.
