Yes you can. From within the ‘More’ section you can configure which programs appear as default every time you open the software. To do so - click the ‘Edit’ button in the top-right hand corner and the following screen will appear.
To arrange which buttons you wish to appear as the default, drag them into the bottom section. You can also change which order you wish them to be in. Just remember the items you place in the bottom main tab will be your desired default buttons. Simply when you are finished, click the ‘Done’ button.
