How do I build brushes with tiles?

I'm trying to build a library of brushes in Construct using tiles and I'm not sure if this is possible. Because of the tileset I'm currently working with, an auto-tiler isn't going to work, so I need to place things down by hand which is time consuming but gives a much nicer finish.

I thought Tiled would have this feature but I can't for the life of me find it, and their forum is down.

If anyone knows how to build tile brushes in either Construct 3 or Tiled, I'd love to hear it.

For the record, GameMaker 2 has the brush builder, which is perfect for this sort of thing, but I'm not going to transition over to a different engine for the sake of saving a bit of time tiling. I did try to build a tileset in GM2 and export it, but no luck (surprise surprise) : docs2.yoyogames.com/source/_build/2_interface/1_editors/tilesets.html

Cheers

Here is the manual:

construct.net/en/make-games/manuals/construct-3/interface/bars/tilemap-bar/tilemap-brush-editor

hmmm, I already read the manual, but as far as I can tell, that's only referring to auto-tiling, which I mentioned in my first post is not something I want.

However, words are important. I was searching 'brushes' and 'libraries' in Tiled docs, but it turns out 'stamps' was the word I needed.

Found what I needed after all that.
