Flipping an anchored object horizontally relative to spine
Hi everyone!
I'm working with an anchored object whose location depends on the spine of the book, like this:

To make things easier I created an Object Style and it moves perfectly.
The problem is that I need this object TO FLIP HORIZONTALLY every time it changes to a left or a right page, like this (it's literally a dotted line with a circle end shape):

I tried to set this condition in Object Styles (corner options) and Anchored Object Options, but I don't find an way that would work automatically. I got to set everything manually, but this creates many mistakes on the workflow.
I would be grateful if someone could share with me some ideas or creative solutions.
Thanks in advance.
