How to remove or replace blocks on an existing build with the new build interface?

[Batavium]

I have “acquired” yeah I stole it a rather nice ship and I like to make some adjustments to it.

In the old build interface I used to be able to quickly replace or remove blocks from a ship without removing the other blocks that make up the ship.

So let say I want to remove all Power Reactors how do I do this in the new build interface?

And let say I want to replace all grey hull for green hull. How do you do that?

Because I am at a complete loss on how this is done now.

I completely looked over that like a dozen times.

My brain only saw the first box with copy brush, copy selection, paste, load and save.

The bit below SEARCH did not register. Running StarMade at 1280x800 also does not help.

Thanks a lot.
