If you would like to bulk-edit the style/layout of your personnel tiles, make the changes you would like to one personnel tile. Once you make the changes to one tile, go to the 3 white dot menu of the tile you made the changes to and select Apply Player Layout.

Once you click Apply Player Layout, you can either select all of your personnel tiles or select individual tiles to apply that layout to.

Once you click save, that layout will be applied to all players that you selected.
