Instead of copying objects, you can choose Page > Duplicate Page from the menu.
Can you please explain your goal more clearly? Are you trying to use the objects on different pages in different ways or do you want them to simply appear in the same places without editing on various pages? In the second case, you should consider using Master Pages.
I wish to select my item to copy, then Ctrl+C, then select all pages where I wish to insert, then CTRL+V.
Basic feature, but ms office or libreoffice draw do not care
