Mirror Guides

Imagine a document is 1000x1000 in size for sake of demonstration.
max_width = 1000
max_height = 1000

Pressing a modifier key on the ruler and pulling out a guide like would call a mirror Guide. this would be a guide in the opposite corner or the document mirroring the one you are holding. this would help making measures to the center of the document or too the edges of the document.

guide_1 = event.x()
guide_2 = max_width - guide_1

guide_3 = event.y()
guide_4 = max_height - guide_3

If you pressed on the mirrored one location they would simply flip locations.
hope my made up math is still understandable.

General improvements and additions to guide facilties have been proposed at various times, e.g this among others:

376943 – Guides should be editable with precision by allowing user to input the new value, and they shouldn't only use pixels as units

I’d like to see the ability to specify a guide position as a percentage of horizontal or vertical canvas size and I need to make a UI mock up of that (unless it’s already been proposed).

I think this general area is a stretchgoal somewere.
