Is there such a thing as an App Extension

[mchrenka]

The below ia a "Visualization" extension I wrote to write a value from the window query string into a variable in an app but I can only use it as a chart - i.e. I have do drag the extension onto a sheet for it to work.

How can I use this "application wide" so it is always setting a variable on every sheet without needing to add a chart extension to a sheet?

define( [

        'qlik','jquery'

    ],

    function ( qlik ) {

        var app = qlik.currApp();        

        const queryString = window.location.search;

        const urlParams = new URLSearchParams(queryString);

        const company_id = urlParams.get('company_id');

         app.variable.setStringValue('vCompanyId' , company_id);

         return {

            paint: function ( $element, layout ) {

              $element.empty();

               //..                

            }

        };

    } );

Hey @mchrenka you cannot do this wihtout putting your extension in every sheets. 
An alternative could be create a backend service which open your Qlik app and put the extensions in all the available sheets, automatically, using Engine APIs.
