Loading liberoffice open a macro when the system is turned on

I know liberoffice can be opened when the system is turned on. Can I fix the system so that a macro is loaded when the system is turned on>

There is a possibility to start a macro via command-line, but not for every module of LibreOffice as yo may see in this thread:

Please note, this is not the same as “load LO on system-start”, but the command-line can be put in a script for the autostart-option of the OS.

Using google with libreoffice execute macro command line you may find a lot of references
