Objective Device in Lego Fortnite

How come there is no objective device in the lego maps in UEFN, only Timed Objectives, but in the standard FN maps there is?

I was wanting to make a capture-the-flag or bed wars type game in Lego, but can’t destroy a bed. I appreciate Lego doesn’t want violence in custom maps, but there is violence in the actual Lego FN game, with killing skeletons and such.

Help/Advice Appreciated
