Hello Paascal, and welcome to Seven Forums.
You might give the free program Desktops
a try to see if it may work for you for this.
Desktops allows you to organize your applications on up to four virtual desktops. Read email on one, browse the web on the second, and do work in your productivity software on the third, without the clutter of the windows you’re not using. After you configure hotkeys for switching desktops, you can create and switch desktops either by clicking on the tray icon to open a desktop preview and switching window, or by using the hotkeys.
Hope this helps,
