Waypoints in maps suggestion

From the interview with Jonathan and Mark, it seems they're positive on the option to have waypoints in maps, just dont know the best way to implement it.

I suggest we get X amount of placeable waypoints, and we get to put them down wherever on the map we choose, just like we can place explosives in the Expedition league.
This way GGG doesnt have to figure out a complex way to code in a waypoint system since maps dont have points of interest like the campaign.
And players get to choose which areas of the map they find suitable to return to.
Best of both worlds.
