   - You can make insignias appear only on selected units using `DrawInsignia.OnlyOnSelected`.
   - Position for insignias can be adjusted by setting `DrawInsignia.AdjustPos.Infantry` for infantry, `DrawInsignia.AdjustPos.Buildings` for buildings, and `DrawInsignia.AdjustPos.Units` for others.
   - `DrawInsignia.AdjustPos.BuildingsAnchor` can be set to an anchor point to anchor the insignia position relative to the building's selection bracket. By default the insignia position is not anchored to the selection bracket.
+  - `DrawInsignia.UsePixelSelectionBracketDelta` can be set to use techno's `PixelSelectionBracketDelta` to additionally adjust insignias vertically.
