Dynamically mounted folders are not seen with the Library Network panel browser.
For example /hosts/workstation-name
To workaround this issue create a symbolic link to the host.
You can for example create a /host-link folder at the root level to hold you links
As root create the directory :
Enter the new directory :
In this new directory you can create the link :
ln -s /hosts/workstation-name workstation-name
You can now navigate to the host with the Library network Panel.
Bonus : If you create the same structure on multiple workstations, linked archives can restore on a different system and find the linked media.
