Global Mapper v25.0

OS Mastermap layers stylesheets settings


I believe Global Mapper do not recognize some of OS styles.  (EG there is no style for Ponds and Drains, Meadows) Is there something I can do about? For now part of map is just transparent. My background is salmon pink on the image below.

Is it possible to enter additional styling to current one? Not sure how I can see or modify only single layer if I want to (EG house number label sizing), without changing the rest of them.

Will be grateful for advice.
OS offer stylesheets here (QML for QGIS or SLD for GeoServer):
How to apply them to Global Mapper?
