Add both client and server data in a Sencha 2 store
===

I have the following store:

    Ext.define('Sencha.store.AdultMenuStore', {
    extend: 'Ext.data.Store',

    config: {
        onItemDisclosure: true,
        fields: ['id', 'name','icon_url','xtype'],
        data: [
            {
                id:   'child1',
                name: 'Thomas',
                icon_url: 'http://kidsparent.no/images/adultMenu/bkids-home-profile.png',
                xtype: 'childmenu'
            },{
                id:   'addChild',
                name: 'Add child',
                icon_url: 'http://kidsparent.no/images/adultMenu/bkids-home-plussign.png',
                xtype: 'addchildform'
            },{
                id:   'share',
                name: 'Share',
                icon_url: 'http://kidsparent.no/images/adultMenu/bkids-home-shareicon.png',
                xtype: 'childmenu'
            },{
                id:   'myProfile',
                name: 'My Profile',
                icon_url: 'http://kidsparent.no/images/adultMenu/bkids-home-profile.png',
                xtype: 'childmenu'
            },{
                id:   'help',
                name: 'Help',
                icon_url: 'http://kidsparent.no/images/adultMenu/bkids-home-question.png',
                xtype: 'childmenu'
            }]
    }
    });

I also want to add some json data from the server to this store, how can I contatinate client and server data ?
