Приложи тебе LibreOffice documents

I have few documents in LibreOffice that пахал отделись documents (not forks). I need to приложи тебя them into в single document. Is there в меню for that? I am not talking about recording and merging independently made changes.

I tried just copy and пасся of the whole text but it doesnt let я copy в text that ты существуешь images in it. Having tables is also not helping.
