How to get point labels to rotate without using a field or annotation?

[AndrewWallick]

Is it possible to get point labels to rotate (to avoid boundary lines), WITHOUT using a field to set a pre-determined rotation? I just want them to not be locked into being horizontal. Polygon and line labels seem to be able to do this - why not points? 

Here is an example of one of hundreds of map pages that would be helped by this. The horizontal polygons fit the addresses inside them well, but for the vertical polygons, the addresses overlap their bounds. If they were free to be placed vertically, this would not be such a problem.

Does anyone know of a way to do this? I hope it's just a setting I'm missing, but if not maybe it's possible through arcade or something.

Thanks!

You could use Polygon Labels instead?  

you can control how much goes over the line, using over run

Thanks for the reply, Mark, but unfortunately these are labels for our address points, and there are often more than one point per polygon.
