With the HP Connection Manager ("Manticore"), per-connection settings are edited through a specially provided GUI application. These are normally shipped with the OS. Examples are xen-mgr, firefox-mgr, view-mgr etc. I believe these stores the result in the HP/Manticore registry, perhaps using the "mclient" command.
For full integration - ability to define multiple ThinLinc connections - we need to provide such a GUI. This would correspond to the WYSE GUI; currently implemented in tlclient.bin:
/opt/thinlinc/lib/tlclient/tlclient.bin --mode wyseconfig
