Or look into using multi-storey walls.
A wall height can be greater than the storey it is on and it can be set to display on multiple storeys in plan.
Then you need just the one window/door opening.
Easy if the wall is all the same material.
If the material varies at different heights then you want to look at using a complex profile wall.
In 22 & 23 you can even set modifiers in the complex profiles so you can adjust the heights and thicknesses of the different materials in each placed wall instance.
