Modal mass in Staad connection update 9


I believe there's a problem in defining the modal mass in the physical modeller, since it allows taking the mass out of the gravity cases, and you cannot add additional masses as from snow or live loads, it was achievable in staad update 8 but isn't the same in update 9. kindly guide me how this can be solved without detaching the physical model?

Thank you!

Kind regards,
