How to set the pivot point (center of an object)

Is it possible to set the center of an object? For rotation I can use the cursor but for other things it is sometimes usefull to adjust it. I haven’t found anything for this.

if you want to move it, go into edit mode, select all the vertices and move them, the center will stay where it was.

you can do this in the edit buttons (F9)

use “Centre New” or “Centre Curser”
