Rotating a drawing within a viewport

[Arch]

Is there any way that I can set up a viewport that rotates the shown drawing by a specific angle without changing the design layer drawing?

An example would be to fit a drawing on an A1 sheet by rotating the view when the original North South orientation doesn't fit so the viewport will show the drawing with the North South orientation at say, 45?.

I hope this makes sense

Thanks
