How to change Qml "model Property" for multiple C++ Models - c++

Question

the code below shows two C++ QStringListModels.
"model" is integrated into the main.qml file as "myModel" and "model2" is integrated into the windowLoader.qml file as "myModel2".
The View of "MyModel2" is loaded when you click on an item of the View of "myModel".
My Question:
If there would be a "myModelX", is it possible to change the model property from windowLoader.qml which has the value "myModel2" or do I have to write a windowLoader.qml for every Model?
main.cpp
#include <QGuiApplication>
#include <QQmlApplicationEngine>
#include <QQmlContext>
#include <QStringListModel>
int main(int argc, char *argv[])
{
QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
QGuiApplication app(argc, argv);
QStringListModel model;
model.setStringList( QStringList() << "foo" << "bar" << "baz" );
QStringListModel model2;
model2.setStringList( QStringList() << "a" << "b" << "c" );
QQmlApplicationEngine engine;
QQmlContext *context = engine.rootContext();
context->setContextProperty( "myModel", &model );
context->setContextProperty( "myModel2", &model2);
const QUrl url(QStringLiteral("qrc:/main.qml"));
QObject::connect(&engine, &QQmlApplicationEngine::objectCreated,
&app, [url](QObject *obj, const QUrl &objUrl) {
if (!obj && url == objUrl)
QCoreApplication::exit(-1);
}, Qt::QueuedConnection);
engine.load(url);
return app.exec();
}
