How to edit UserSymbolDirectories path in Windows registry from QSPICE GUI

I moved the location of my simulations which caused an error message about an inaccessible folder at the old location, even though the simulation ran correctly. I searched the registry for the old path and found it at Computer\HKEY_CURRENT_USER\Software\Marcus Aurelius Software LLC\QSPICE[Preferences]\UserSymbolDirectories. Changing this registry entry to the new path resolved the error messages. Is there no way to edit the path contained in the registry entry UserSymbolDirectories without having to find and edit it in the Windows registry?
