To answer your question, yes there are jigs.

For my mandolins, a jig wouldn't be accurate every time, because I vary the height of the top arch a little bit, and I sometimes vary the bridge height a little bit. Either one of those will change the neck angle.
Unless your arch is the same height every time, your overstand height is the same every time, and you use the same target bridge height every time, you can't use the same neck angle every time, so you can't make a jig that is accurate every time unless it is adjustable, and you never make any mistakes adjusting it.

I measure the bridge height I need with a variable angle gauge, then based on a tangent calculation, this guy helps me through the bandsaw to get it pretty close.

Russel , I always use the V notch and I do all the process
with the circular saw .
