Unable to set custom UUID for installer on Windows

I want to set fixed UUDI for application on Windows during creating of installer using QTIF. I did't found

In function PackageManagerCorePrivate::registerPath() that is located in /src/libs/installer/packagemanagercore_p.cpp.

QString PackageManagerCorePrivate::registerPath()
{
#ifdef Q_OS_WIN
QString guid = m_data.value(scProductUUID).toString();
if (guid.isEmpty())

{ m_data.setValue(scProductUUID, QUuid::createUuid().toString()); guid = m_data.value(scProductUUID).toString(); writeMaintenanceConfigFiles(); // save uuid persistently }

QString path = QLatin1String("HKEY_CURRENT_USER");
if (m_data.value(QLatin1String("AllUsers")).toString() == scTrue)
path = QLatin1String("HKEY_LOCAL_MACHINE");

return path + QLatin1String("\\Software\\Microsoft\\Windows\\CurrentVersion\\Uninstall
")
+ guid;
#endif
return QString();
}

This function check "scProductUUID" if it there then put it. But "scProductUUID" can't be provide via config, because it is not added in valid keys list. (Parameter "ProductUUID", exist but not available for input).

The list of parameter available in "settings.cpp":

QStringList elementList;
elementList << scName << scVersion << scTitle << scPublisher << scProductUrl
<< scTargetDir << scAdminTargetDir
<< scInstallerApplicationIcon << scInstallerWindowIcon
<< scLogo << scWatermark << scBanner << scBackground << scPageListPixmap
<< scStartMenuDir << scMaintenanceToolName << scMaintenanceToolIniFile << scMaintenanceToolAlias
<< scRemoveTargetDir << scLocalCacheDir << scPersistentLocalCache
<< scRunProgram << scRunProgramArguments << scRunProgramDescription
<< scDependsOnLocalInstallerBinary
<< scAllowSpaceInPath << scAllowNonAsciiCharacters << scDisableAuthorizationFallback
<< scDisableCommandLineInterface
<< scWizardStyle << scStyleSheet << scTitleColor
<< scWizardDefaultWidth << scWizardDefaultHeight << scWizardMinimumWidth << scWizardMinimumHeight
<< scWizardShowPageList << scProductImages
<< scRepositorySettingsPageVisible << scTargetConfigurationFile
<< scRemoteRepositories << scTranslations << scUrlQueryString << QLatin1String(scControlScript)
<< scCreateLocalRepository << scInstallActionColumnVisible << scSupportsModify << scAllowUnstableComponents
<< scSaveDefaultRepositories << scRepositoryCategories;

Here "scProductUUID" just missing.

Since functionality is there, but I can't setup it because of missing value in white list I assume this is a bug.
