How can I do waypoint movements in XCOM 2 (console version)?

In an official Xcom 2 news posting regarding an update to PS4 and Xbox One versions, the first item listed under "GAMEPLAY" is

Waypoint functionality added.

I played the Xbox One version last night and was able to add a waypoint by pressing and holding the A button; presumably the PS4 version's X button would support the same functionality.

At of the time of this writing, I couldn't find any updates to either the PS4 or Xbox One online game manuals and I don't remember seeing any in-game notifications indicating that this new feature was available.

It doesn't sound like you can.

I played this game on PC, so I know what you're talking about. I looked around a bit, and the best evidence I found was actually this Reddit thread, entitled "The lack of ability to create waypoints on consoles is a pretty big oversight".

Since so many people on Reddit are so eager to tell people that they're wrong and that they're idiots, I think someone probably would have chimed in to say that waypoints are possible if that were the case. Instead, we have a bunch of people complaining about the lack of the feature while other people tell them that it's not needed (and that they're idiots).
