How to change occluder type in a map?

[YAKO SOMEDAKY]

I'm not exactly sure if this is the place to ask, but I need to ask somewhere.
The question is is there any video or tutorial that allows and teaches how to change the type of occluder, without having to redesign it.
Example: Let's say I had the Terrain Occluder Tool and I made a circle on a pillar, it's ok that it will block the view but not the movement, i.e. I would cross it, but instead of redrawing I just want to change this terrain-type occluder to a wall-type occluder.
if there is any place or means, thank you in advance!

Select all of the points in the occluder you want to change and then whilst holding CTRL click on the occluder you want to change it to. See video twenty three here https://www.fantasygrounds.com/forums/showthread.php?55797-How-do-I-in-Unity
