LibreOffice. Windows 10. Taskbar. One button for all documents

[Shumway]

I’ve switched off the grouping on the taskbar in Windows. And LibreOffice opens new button on the taskbar for each document now. Usually I work with many documents at the same time, but also there are opened browsers, file manager, mails and so on. So, the buttons on the taskbar become very small and unuseful (because I can’t see the name of document).

And I can’t find the settings, which allows to create only one button on the taskbar for LibreOffice.
How to do this?

There is none.
