Change foliage instances WPO with blueprint

Hello. I am trying to do some similar work with all foliage instances in my level like this guy was doing here - How to get position of procedural foliage? but I can’t seem to be able to change the “Evaluate world position offset” boolean or the WPO Disable Distance for any of my foliage instances. I am printing out all the foliage instance names but no luck in affecting any of the WPO settings. Can any blueprint gurus help me figure out how to edit my foliage instance WPO settings? Thanks!
