Connect to secure WMS with Active Directory Authentication

Main question:
Is it possible for Global Mapper to connect to a WMS service that's been user/pass redtricted, by parsing these credentials within the body of the WMS url? For instance, connecting to a WMS from GeoServer.

Related Question:
I have WMS & WFS services on Portal for ArcGIS that I'd like to connect into Global Mapper without having to expose them publicly. Currently, global mapper doesn't support connecting to ArcGIS rest services that are authenticated through the active directory. Does anybody now if this is in the development pipeline?
