FFS - assistance with AGVs

Hello,

Is there a basic tutorial on AGVs in Factory Flow Simulation someone could provide? Including any preferences and user variables i need to define. I'm also using 2022x 3Dx so any new features beyond that release I unfortunately cannot use. 

I've traditionally used mobile storages but for the use-case i'm trying to do, I believe AGVs are better suited.

My use-case is quite simple: i'm trying to do is determine to have a single transport solution carry products from several stations in a loop. I would then like to study how many transport solutions I require. If I can define the transport flow for one AGV, and then duplicate or increase the quantity without needing to change my flow that would be ideal. 

I'm having trouble just defining a mobile storage, the define Pathway command I get a non-valid selection on a 2D Area i've defined.

I also tried using the generate path system, which allows me to create a pathway. But when I try to add an AGV decision zone, it doesn't allow me to select the pathway.
