Can maps have custom DYK (Did You Know) Files?

[JC_Denton]

I'm back to expanding a map (will likely post within the next week assuming play testing goes okay), and came across this again. I don't suppose there's any chance of it being added to the next patch, whenever that may arrive? I think it's an opportunity to add character to regional maps.

(Or maybe it works in mods now, but not maps?)
