Writer -Default option on MS taskbar

There are 2 temples I almost exclusive use. The basic “Writer” and a “Wide Margin” template. More time than not I want the wide margin one, however with the app in MS taskbar ittaskbar.jpg defaults to the basic template, and I have to right click and choose the wide margin to open it. Even trying to place the wide margin template on the taskbar still forces the choice. How can I make wide margin the default temple, without having to right click and select? For now I have to click on a desktop shortcut for the wide margin template (see attached). Thanks
