Is there a way to change the category of a sub building?

[City Builder]

For example I built a great hall that has the main hall and two smaller halls on either side but did it as part of the great hall. Is there a way to remove them from the great hall category and change one of the little rooms into a different sub building such as a treasury without having to tear it down and replace it new as a treasury sub building?
Thanks

You can't change individual parts, no. You can only change the entire sub-building type.

OK that's what I thought but thought to ask in case I'm just not seeing it. Will just have to tear it out and rebuild when I have more resources.

I would love the ability to juggle parts to other sub buildings. I often build something only to realize it would make more sense as part another sub building instead.

On a side note this is ...

Great Hall (Blue) -- Vestibule, Door, Decorations

Bailiff Office (Red) - Vestibule

Tax Office (Light Brown) - Manor Tower, Major

Watchpost (Red, not built) - Vestibule

Treasury (Green, not built) - Manor Hall, Minor

NOTE: The Bailiff Office was initially built as a "Free Build" just to internally connect the Great Hall and Tax Office.)

That's about the cheapest and most streamlined (but still aesthetically pleasing) starter Great Hall I've come up with.
