I am currently using Passolo 2022 22.0.254.0.  Once I have obtained an IPslSourceList, I can read the current Virtual Folder Path via the VirtualFolderPath property, but attempts to write to this property fail:

ERROR: System.Runtime.InteropServices.COMException (0x0000F18D): Unable to write read-only property.
at System.RuntimeType.InvokeMember(String name, BindingFlags bindingFlags, Binder binder, Object target, Object[] providedArgs, ParameterModifier[] modifiers, CultureInfo culture, String[] namedParams)
at System.RuntimeType.ForwardCallToInvokeMember(String memberName, BindingFlags flags, Object target, Object[] aArgs, Boolean[] aArgsIsByRef, Int32[] aArgsWrapperTypes, Type[] aArgsTypes, Type retType)
at PassoloU.IPslSourceList.set_VirtualFolderPath(String)

Is this a bug?  Writes to other properties succeed.  If this is intended, is there an alternative method for moving a source list to a different virtual folder?
