I have hundreds of annotation stored in a GDB, with either Horizontal alignment to left or right. These annotations also have a Callout -> Background -> with only Leader line symbol.
However, I have quite a few annotation where Horizontal alignment do not match the Leader line. For example, I can have a Right Horizontal alignment with a Left Leader line. Is it possible to calculate the HorizontalAlignment in the attribute tables with a Python expression taking into consideration the Leader line position?
