Conditional Fields with multiple lists

Hi,

I use the conditional field option. I would like to show different lists of options for the child field based on the selected option from the parent field.
Currently I can only show one list of options based on the selected parent option.
Eg. If the billing address is option 1, I want to show a list of cities for the city field. If the billing address is option 2, I want to show another list of cities for the city field.

Hope it is clear.
Thanks.
