Non movable interest points: EQS, Blackboard list or map function?

My maps have a few interest points that the AI has to interact with, what would be the appropriate way to pass this information to the Behaviour Tree?

The interest points are not movable, so an EQS could run once and set it (where? blackboards don’t support arrays of Locations, right?), or the level blueprint could retrieve them on begin play and set them, or even the AI Controller.

What would be the best option?
