Can you remove these columns?

I added some larger sections to my base and are left with these doorway column remnants. Is there any way to remove these so I can have one large open area?

There is a way, I've been told, though it might be a bit of a challenge, at least, that's what I gathered.  A discussion of this came up briefly back in April, I think it was, over on the Discord channel for base builders.  I think @Easter Bunnyprovided some of the info.   I never pursued it as there were options already in play in my base design that allowed me to work around this.

Those aren't columns, those are the room. That's the floor and ceiling filling the space.
