Change Active Tilemap sequence

Pretty simple question;

How do i change the sequence at which tilemaps appear in the editor?
Like this: Screenshot by Lightshot

What I want, is for SolidGround to be the default tilemap (the first in line). It doesnt seem to change alphabetically, nor when i change the order ingame. In some scene, one tilemap is first, in another scene, it’s a completely different one. I tried figuring it out but at this point it seems completely random.

It’s a minor annoyance, but is there any solution?

Seconding this, badly in need of solution
