How to pass the 'pressed' mouse event to another object which is created only after press event triggered

[MKCV]

By setting 'propagateComposedEvents' to true, able to pass the mouse event to already present underneath mouse area. But is there a way that if we click on RectA mouse area then RectB is created from that point under RectA and pass the 'pressed' mouse event to RectB.

import QtQuick 2.15
import QtQuick.Controls 2.15

ApplicationWindow{
    id: applWindow
    visible: true
    width: 300
    height: 300
    x:100
    y:100
    

    Loader{
        id: loader
    }

    Component{
        id: rectBComponent
        Rectangle{
            id:rectB
            color:"green"
            width: 50
            height: 50
            z: -1  // to create rectB below the rectA

            MouseArea{
                id:rectBMouseArea
                anchors.fill: parent
                onPressed:console.log("rect B recevied press event") // handler to receive the press event
            }
        }
    }

    Rectangle{
        id:rectA
        color:"red"
        width: 50
        height: 50

        MouseArea{
            id: rectAMouseArea
            anchors.fill: parent
            propagateComposedEvents: true
            onPressed:{
                loader.sourceComponent = rectBComponent // create rectB when rectA is pressed
                if(loader.status == Loader.Ready)
                {
                    loader.item.x = rectA.x
                    loader.item.y = rectA.y
                    loader.item.width = rectA.width
                    loader.item.height = rectA.height
                    mouse.accepted = false // not accept mouse event and pass it to below object
                }
            }
        }
    }
}

Please clarify that can I pass the mouse event to another object which is created after the mouse event is triggered. Thanks in advance.
