CentOS - Mar 2020 - Problem setting keyboard shortcuts for more than 4 workspaces.

Hi,

Does anyone know how to set keyboard shortcuts for more than 4 workspaces?

If I goto settings -> devices -> keyboard I see "Switch to workspace
{1-4}"
I have virtual workspaces configured for 12. I would like to set keyboard
shortcuts for all 12 workspaces.

Google shows numerous solutions for ubuntu but I cannot get any of them
to work on Centos 7 with gnome 3.

Regards,
