How to disable Credit card expense type mapping?

Hi Everyone,

If we want no default expense type on Credit card transaction, can this be achieved by disabling below option on Expense report template setup? or even after disabling this Transaction Details mapping rule on Credit card program setup need to be left blank? Basically we are exploring an option to not default any expense type on Credit card transactions and so Employee can be forced to select the appropriate expense template and type.

Thanks in advance.

Regards,
