A broader range of Workspaces shortcuts

I would like the possibility of increasing the number of Workspaces shortcuts that appear after the double Crtl command. Now there area 10 numbers that can function as shortcuts (0-9). Could it be possible to expand those to basically any other key on the keyboard? In this way it would be easier to access very quickly to any of the Workspaces, when there are more than 10.

Thank you.
