More alive than the living.

One of the simplest options is to place any static object (for example, a stone), select it, find the "Shared" line in the left panel, and change the value using the ellipsis to the desired one (you can find the desired value on my map, for example, or find it yourself in the list). Also, note that the editor supports copy-paste: you can open my map, copy a pit, open yours, and paste it.
