Anyone got startup.lsp to be loaded at startup in CorelCAD 2020?

Hi! I'm struggling with my lisp routines to be loaded at startup. I have a startup.lsp file in a supported path, which can be loaded manually. However, CorelCAD 2020 do not have anymore the command addins, which should be used to let it know to autostart a lisp file.

So, someone knows how to solve that? I already contacted the support, but they aren't able/willing to help...
