Is it true autorouter cannot handle 45 degree angles?

First of all, I am very very new to Cadence. I've done some board design and layout in KiCad before for a mixed-signal project.

My colleagues are telling me the default autorouter in Cadence can't handle 45 degrees off of a pin, which basically means we can't use the autorouter for a BGA device that can only be broken-out/fanned-out with two 45 degree angles.

I was told the GRE (from googling I think this is the Global Routing Environment) can do 45s, but needs a lot more hand-holding/manual-interaction.

I have more questions, but I don't want to make this post too long and complex.

Is the info I'm hearing in work meetings correct (they say the 45s only get implemented by post-processing 90s with a 'miter' operation)?
