Can't you just have something that fires off after the start of layout action? Like maybe a function called in start of layout, and the function handles the Anchor?
Or perhaps, have the HUD/UI layer that is anchored be invisible then after a few seconds anchor everything and then fade them in?
Mainly just brainstorming ways to give you time to get through start of layout first. I haven't messed with it much myself as I haven't had much time today. Maybe someone else has an idea.
