Rotary axis limitations

Hello, I am practicing at Fusion 360 and I found something interesting. I have been looking around quite a lot to find a solution and I am giving up... the problem is as follows:

If you want to make something like a helical or bevel gear, the forth axis is not being very compliant.

I tried all kinds of strategies, but I just can't manage to make the program to run along the gear teeth and machine the profile of the tooth ( best I got is a simple slot pattern with 2D pocket). The Rotary extension gives some options, but they are limited. In there  I also  didn't find a way to add multiple passes (that's the first thing I noticed) and there are 3 options for the toolpath :

-Spiral

-Line

-Circular

Non of them are practical for helical gears for example or other helical elements. It would be nice if the "spiral" could be controlled so you can set the starting angle of the helix and then it getting distributed as a  the "line" toolpath. that would give a lot of flexibility and also I had some problems with setting the geometry constraints. it would be nice to just set those on the 3d model instead of making patches and etc.
