Spawn custom locations

Hello

Is there a way to customize the spawner positions besides the incremental "position settings" in the inspector. I want to spawn 10 randomized
objects in a "z" formation with 1 unit spacing. I have other formations as well I need to spawn (all include at least one right angle).

I have investigated spawning along a path but then I would have to ditch useing Core Gamekit as my spawner.

Thanks,

Raymond
