Remember multiple window positions in windows

in calc (and i assume writer, too) if i hold down the right crtl+shift and close the window, it remembers the window position. if i then reopen the document, the window position is saved, even upon reboot, and isn’t required again. also, the currently/last edited worksheet and cell position is also saved, regardless of ctrl+shift close.

what i want is to be able to save the window position when i have multiple windows of the same document open - how do i do this?

perhaps my explanation of my question isn’t clear

in calc, when i go to the Window menu and New Window, it creates a new window of the same document, where i can update the same file

what i want, is to be able to auto-start calc and have both windows open at the same scroll position and worksheet as when it was closed

is this possible via a script native to libreoffice?
