How to reference a group of actors in level blueprint?

I want to get a reference to multiple actors placed in a level in my level BP, either grouped or ungrouped ones, how should i do it without getting a separate reference from each individual actor (since that would be tedious and inefficient)? Any advice would be appreciated!

Select them All inside your level, Then go to Level Blueprint and Right click, Then Select Create Refrences to your 99 Actors, like this image below

getAllActorsofClass and store into an array.

Or use gameplay tags, and find all actors with tag.

The gameplay tags worked! Thank you for your replies!
