How to rotate view 180 degrees?

Question

Adobe Illustrator

I'm laying out a layout with one artboard. Half of the layout is turned upside down. To edit such a layout, you have to periodically flip it 180 degrees. I do this with the help of transformation: I select all the objects and rotate them 180 degrees. However, since the center of such a group does not coincide with the center of the artboard, after the flip, all elements are shifted together. You have to adjust them and put them in place every time, which is annoying, and there is a risk that something will fly off somewhere due to an oversight.
Is it possible to somehow expand the viewport for the convenience of work and not to do unnecessary operations on the objects themselves?

Answer 1

In such cases, I insert linked *.ai or pdf into the final layout, and comfortably edit the sources with a bunch of necessary layers without fear of hurting the adjacent layout fragment. It is very convenient when there are several identical layouts on a sheet.
