Currently, Layer Combinations can only be updated or redefined by selecting and deselecting layers by name within the layers menu.
It would save so much time & be so much more intuitive if they could also be redefined via directly matching currently displayed layers.
Very often exactly the layers you need displayed for a purpose are identified visually, on the fly, by right mouse click menu using "hide layer" command.
Remembering after the fact all those layer names you adjusted on the fly and duplicating the selection process again within the layer menu is pretty inefficient, and error prone (easy to miss some layers, as not the same visual feedback that you get making selections directly within the working view)
