Macro - Set Actor Hidden In Game

G’day

I’m hiding and unhiding a lot of actors for construction simulations so have been trying to create macros to reduce the amount of BP’s needed.
I can use the set actor hidden in game node and connect multiple actors, but cannot covert to a macro (to add other functionality for the timeline sequence) and maintain the ability to connect multiple actors to a single input. I hope someone might help me understand why this is so.
